About this product
An analog water pressure sensor with a G1/4 inch threaded connection, made to fit into water lines and fluid systems. It outputs an analog signal that changes with pressure, so it can be read by the analog input of a microcontroller such as Arduino or ESP32 after scaling. Check the supply voltage and output range before connecting.

Frequently asked questions
Can I read it with an ESP32?
ESP32 ADC pins accept at most 3.3 V. Check the sensor's output range, and if it can exceed 3.3 V, use a voltage divider before the ADC pin.
Does it need a separate power supply?
Yes. An analog pressure sensor needs a supply voltage and a ground connection in addition to the signal line. The required voltage is given in its datasheet.
