IDC TDS sensor

Do you want to check the quality of your water at home or at school? Use a TDS (Total Dissolved Solids) sensor compatible with micro:bitThis analog sensor allows you to measure the amount of dissolved substances in water and is suitable for projects focused on testing water quality - for example, in the home, hydroponics or school experiments.

The sensor supports 3,3-5,5 V power supply and generates an analog output signal of 0-2,3 V. Thanks to the alternating signal, there is no polarization of the probe, which increases the service life and measurement accuracy. The waterproof probe is designed for long-term immersion in water. It can be easily connected to expansion boards MB1, MB2, MB3 or to a universal fixture. Programming takes place in the MakeCode environment.
