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 […]
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 […]
