Description

  • Chirp Plant Watering Alarm and Soil Moisture Sensor
  • Features a plant watering alarm chip
  • Chirps when the soil dries out
  • Uses capacitive humidity sensing technique

The Chirp Plant Watering Alarm and Soil Moisture Sensor uses capacitive humidity sensing technique that does not interfere with the soil and does not cause corrosion of electrodes, unlike resistive sensing. Chirp is Open Source and totally hackable - you can download and fiddle with the firmware or use it as a standalone moisture sensor.

Chirp Plant Watering Alarm and Soil Moisture Sensor - Click to Enlarge

Chirp is a plant watering alarm - as simple as that. You put it into the soil near a plant and it emits a tiny chirp when the soil is dry, reminding you to water the plant. The alarm level can be set for each plant individually.

As water is consumed by the plant, Chirp will detect the low moisture level and will start to emit rare short chirps. As more water evaporates, Chirp will increase the alarm rate.
