voltage: 5 VDC dimensions: 65 x 20 mm weight: 5 g Arduino compatible soil moisture sensor + water level sensor module. This package includes a water level sensor and a soil moistur e sensor. If the boards have water covering the sensor parts, an analogue value will be available at the "sig" connection. The water level sensor can sense up to 4 cm of water. This way, you can track whether or not your aquarium or your pet's water bowl still has enough water in it. You can use the soil moisture sensor to keep an eye on your plant's soil or the environment of a terrarium for example. NOTE: TO UTILIZE THIS SOIL SENSOR, AN ARDUINO (OR OTHER MICROCONTROLLER) IS REQUIRED AND IS NOT INCLUDED. Project ideas and code are not included, but are readily available online.
