These days, some development boards come with an absolutely astounding variety of hardware. The EESP32, a tiny LoRa board with WiFi, Bluetooth, a transceiver that spans a large portion of the UHF band, and conveniences like OLED displays and an abundance of GPIO, are a perfect example. What about the documentation and firmware, though? Basically, do not say anything at all if you can not say something kind. Better yet, just take a roll. That is not true for every LoRa dev board available, of course, but [Rop] found that to be the case with the Heltec HTIT-WB32LA. This board needed some assistance to get over the line, but it has all the bells and whistles and would be ideal for LoraWAN and Meshtastic applications. Based on his fork of the RadioLib library, which includes a library that significantly lessens wear on the ESP32's flash memory, [Rop] has contributed a fair amount to this end. The library supports all of the hardware on the board, including the pushbutton, display, power management, battery charging, and blinkers, in addition to complete radio support. Many sample applications are included in [Jop], ranging from the minimal requirements to spin up the board to a fully functional spectrum analyzer. It is a wonderful piece of work and a wonderful way to support the LoRa community. And if you want to put one of these modules to work, you’re certainly in the right place. We’ve got everything from LoRaWAN networks to the magic of Meshtastic, so take your pick and get hacking.

Exploring LoRa Modules: SX1262, ESP32, and More for Long-Range IoT Communication

In today’s rapidly evolving world of Internet of Things (IoT), the need for wireless communication devices is on the rise. One of the most popular wireless communication technologies used for IoT applications is the LoRa module. In this blog post, we will discuss the LoRa module and its various components such as the SX1262, ESP32, Wi-Fi, Bluetooth modules, and some popular LoRa modules such as the Lorawan-LPS8, Dragino LoRa Bee V1.1, and Hoperf RFM95–98(W).

What is a LoRa Module?

A LoRa module is a low-power, long-range wireless communication module that uses the LoRa modulation technique to enable long-range communication over the air. LoRa stands for “Long Range” and is a proprietary wireless technology that enables long-range communication between two devices without requiring a high-power transmitter or receiver. This technology is designed for low-power, long-range communication with a low data rate, making it ideal for IoT applications.

This connectivity option enables the device to connect to the internet and send and receive data from other devices on the network. The Wi-Fi module can be integrated into the ESP32 or provided as a separate module that can be connected to the device via an interface such as SPI or UART.

Bluetooth Module:

The Bluetooth module is another important component of LoRa modules that enables the device to communicate with other Bluetooth-enabled devices. This connectivity option is ideal for short-range communication between devices such as smartphones, tablets, and other IoT devices. The Bluetooth module can be integrated into the ESP32 or provided as a separate module that can be connected to the device via an interface such as SPI or UART.

Lorawan-LPS8:

The Lorawan-LPS8 is a compact, low-power LoRaWAN module that is designed for IoT applications. It is based on the SX1262 and features a built-in GPS, making it ideal for tracking applications. The module supports LoRaWAN 1.0.2 and provides up to 20 dBm of output power. It also features a built-in antenna, making it easy to integrate into devices. The Lorawan-LPS8 is an excellent choice for applications that require long-range communication with low power consumption and GPS tracking capabilities.

I've explained all the issues about the usage of the two user-available SPI peripherals and about the battery/USB/external power usage. Thanks to #digitspace for giving me those board to experiment with. Read the full article in the bio.

Tree moisture meters

I had an interesting time last week attending the 4th Trees, People and the Built Environment (TPBE4) conference run by the Chartered Foresters.  Some interesting sessions and worthy sentiments but I didnt get any sense of urgency. 

A couple of the sessions addressed the use of technology in the urban forest.  For example Nadina Galle talked about the Internet of Nature and the application of Smart City thinking, a city-wide network of sensors using AI to make better decisions about deployment of resources.  GreenCityWatch have developed tools to create an inventory of urban trees using commercial high-resolution imagery and some open-source image analysis tools.  Treemania aims to provide a network of moisture sensors to alert council staff to the need to water newly planted trees.   

I have a love-hate relationship with these ideas.  On the one hand they too often seem like expensive, irrelevant and authoritarian structures, all bright and shiny to lure unsuspected city councils desparate to show they are doing something towards the climate emergency.  On the other hand, I’m a bit of a geek and love the idea of sensors to bring the life of trees to wider notice.   Moisture sensors also fit well with a planned platform to assist citizens to look after new trees, in particular 590 trees being planted in deprived areas of Bristol, part-funded by the Urban Tree Challenge Fund.

Treemania’s sensor seemed from the pictures to use a common capacitive moisture sensor. I thought a remote sensor could be based on a board I’ve planned to use on the boat for remote sensing of water level and battery state.  I’ve also been looking at it as a basis for a remote dendrometer. The board is an ESP32 with integrated GSM module, costing £15 or less.  GSM (2G) is expected to continue to be supported in the UK through to 2025.   Rui Santos has a great tutorial on using this board with Arduino code for just such a project.  A capacitive soil moisture sensor costs a few quid, a temperature sensor likewise.  The board has an integrated socket and charger for a 3.7v LiPo battery.  In use the sensor will only need to report at a very low frequency - maybe only a few times a day, and with the ESP deep sleep mode the device should run unattended for a month or more. Soak testing is underway.

Acquiring a suitable SIM is challenging.  Although mobile internet on a pay-monthly contract is down to £1 a Gb, minimum payment is around £10 a month. Given that only a Kb or so is used for a single  HTTP GET to transmit the data, the device needs only a few Mbs a month.  I found a couple of companies  specialising in IoT connectivity. The cheapest is ThingsMobile, based in Milan and the cost is more like £10 per annum.  Even here, the cost per Mb is 100s of times more expensive than your regular Pay monthly  sim.  It took ages to arrive but works fine and at E0.12 / Mb is pretty good.

So the bill of materials is:

TTGO T-Call ESP32 SIM800L board   

Capacitive Moisture Sensor

DS18B20 Waterproof Digital sensor

3.7v LiPo

waterproof container

Overall cost for the components should be under £40. 

Wiring is straightforward:  The moisture meter needs 3.3v power and an A2D pin  (ADC0) ; the thermometer is a one-wire interface needed a digital I/O pin (Pin25)  with a 4K7 pull-up resistor.  Rui also has a great tutorial on interfacing this sensor.  I got stuck for a while on this, not realising which GPIO pins supported I/O.  Accurate pin-out diagrams and the datasheet for the right variant of board are essential.   A small auxiliary veroboard wired directly to the ESP32 board handles these connections.  The ESP32 board is supplied with a simple aerial which worked fine.  A better quality aerial costs a few quid.

This is the current lashup

Rough sketch of wiring:  R is 4K7 

The Arduino script hard-codes the GPRS parameters, the HTTP parameters to use GET to send the data to the server and the sleep interval.  This code is on GitHub 

Periodic readings are sent to my server where they are logged and graphed and from where alerts can be generated.   A test harness only at present so nothing worth sharing yet.

Summary

The prototype is working.  The moisture sensor needs good waterproofing and seems a bit sensitive to placement.  The power draw of the GSM is quite high high during transmission.  I’m also running a WiFi version and of course its power draw is much less.    It would be nice if the Bristol LoRaWAN network was up and running but that seems to have gone very quiet. 

The main problem is with power.  This board includes a (very small) JST connector for a LiPo and a charger,  For a while it switched happily from USB power to battery and back without manual intervention.   LiPos are small and expensive however and I’m currenly experimenting with 18650 batteries which offer better storage/£ .
