We’ve said it before but it’s worth repeating: rolling your own hardware solution is ridiculously easy these days. If you want to make a network attached environmental sensor, you wire a DHT11 ...

The DHT11 sensor will typically connect to the GPIO pin for data transmission, while the raindrop sensor will connect to an analog-to-digital converter (ADC) since the Raspberry Pi does not have ...

New stuff you need Second micro:bit and battery DHT11 environmental sensor LAST week it was rain. This week, our mini weather station will measure temperature and humidity.

Temperature and humidity measurements are a nice addition to many hobby projects. But [Rajendra Bhatt] makes the point that many of these sensors have a price tag that is well above what most hobbi… ...
