David Booth shared their custom temperature sensor using MQTT and CircuitPython.
via raspberry pi pod and micro:bit base
A custom, low power temperature sensor powered by a Raspberry Pi Pico with an LCD display and WiFi connectivity for integration into an MQTT home automation hub.
For a number of years now, I’ve been wanting to monitor room temperatures across my house to assess the effect of multiple heating sources and insulation efficiency. Best practice would dictate that I have multiple sensors running in parallel to get data points that are relative to one another. For multiple sensors to be running constantly, I’d prefer it to be low powered and low cost to maximise the number of units I can have in the setup. For ease of setup, it would be preferable for each unit to be wireless to allow temperature data collection to be performed in a single location and for each unit to only require a power connection.
