Moisture sensors, relays, and simple code save plants Keeping my houseplants alive used to be a hit-or-miss affair. I decided to build an automatic watering system using a Raspberry Pi, a ...

In this module, a waterproof temperature sensor is used to measure the temperature and relay the measured temperature data to a Raspberry Pi. A software application implemented using the Python3 ...

The raindrop sensor detects the presence of rain by measuring the conductivity of water droplets on its surface. The setup involves connecting the sensors to the Raspberry Pi’s GPIO pins.

The Pi can sink up to 16mA per pin if configured properly. Try that and see what happens. I normally order a few of each sensor so I can try with a different sensor if something is acting up, though.
