Soil Moisture Sensor KIT with Relay Output

Attention, the product is a KIT and therefore you will be given the components to be soldered with an electronics soldering iron and everything needed to recreate the device as shown in the image. The KIT includes easy-to-understand illustrated instructions in Italian.

EXPERIENCE LEVEL REQUIRED medium-low

Assembly and testing by Mectronica STORE is also available by adding quantity 15 of the KIT assembly service which can be purchased separately and adding it to the cart together with the KIT to be assembled.

This humidity sensor is able to detect if the soil is too dry or too wet thanks to a push button switch integrated on the board and a trimmer for adjusting the trigger threshold.

Humidity sensor composed of two distinct parts: a main board and a fork-shaped element to be stuck into the ground. It offers two different operating modes, detecting whether the soil is excessively dry or too wet. This is made possible thanks to a push-button diverter integrated into the board, which, depending on its position, in combination with the adjustment of a trimmer, activates one of the two operating modes. The board can be used, for example, to activate an electric pump and start irrigation. Essential for monitoring soil humidity in agricultural and horticultural crops, allowing efficient irrigation management and better plant health. Useful for those who have a garden or grow potted plants, ensuring targeted irrigation that is adequate for the needs of the plants.

Welding required for assembly. The kit comes complete with assembly instructions in Italian.
