swimming pool robot use 5v power supply natural gas liquid miniaturel water i2c pressure sensor
PS19 pressure sensor is a small general-purpose pressure transmitter designed by Atech sensor. industrial pressure sensor is a standard and most popular sensor applied in air and liquid pressure measuring. A high sensitivity silicon pressure chip is employed in the sensor. The housing is filled with oil for pressure transmission. The most important specification for industry application is long term stability. now it is wildly used in swimming pool robots
