The latest most stable version of my Remote 3G/4G MySensors Gateway. This version is much more stable thanks to the SIM7600G-H 4G HAT (B) for Raspberry Pi, this 4G hat is designed for 24/7 use unlike the HiLink USB dongle used in the previous version. Component list: Raspberry pi Zero WH. SIM7600G-H 4G HAT (B) […]

I’ve setup a number different types of temperature and temperature/humidity sensors. The types that I’ve used are Ds18B20 temperature sensors and DHT11 temperature/humidity sensors. Ds18B20 The Ds18B20 temperature sensor, comes in 2 packages, a TO-92 and a waterproof probe. The TO-92 is useful for making room temperature sensors but the probe is better suited to […]
For the Sensor nodes I’m using the Stemedu LoRa Radio Node V1.0, these are based on the Arduino Pro mini and have an RFM95 LoRa radio on board, they also have a 14500 battery holder making them almost ready to go nodes. The Radio is connected to the board following the same wiring convention as […]
It’s been a while since I posted, last month was busy with getting the yard ready for cattle for the winter. I’ve a few ideas for the winter months, I’m going to work on building a range of sensors. Some Idea’s I have for sensors are: Temperature / Humidity Sensor for Polytunnel Soil Moisture Sensor […]
farmOS provides an API to import sensor data and since I’m already building a farm wide sensor network this looks like a feature I’d like to implement. The farmOS guide https://farmos.org/guide/assets/sensors/ says: “The Farm Sensor Listener module is a general-purpose sensor sub-module that provides a simple “Listener” sensor type. Each sensor asset that is denoted as a […]
In order to monitor sensors a long way from the main farm I’ve built a remote sensor gateway using a Raspberry Pi Zero, an old 3G dongle and an NRF24 radio. I’m only using the NRF24 radio as I had some spare here along with some old sensors from previous projects. These can easily be […]
In previous posts I used mostly off the shelf IOT devices from Tuya, Sonoff and Shelly, these are great becasue they are cheap and easily integrated into many projects. The issue though when you want sensors for custom applications is there are not many cheap off the shelf options. Thankfully there are a few well […]
