Pressure Sensor G1/4 1.2Mpa Analog

This pressure sensor from Seeed Studio measures the pressure of water and other clean, non-corrosive liquids and gases up to 1.2 MPa (12 bar). The housing is made of stainless steel, the connection is a G1/4 pipe thread. The sensor is supplied with 5 V and outputs a voltage of 0.5 to 4.5 V, which is read via an analogue input and converted into pressure.

Important: The output reaches up to 4.5 V. Boards with 3.3 V inputs such as the ESP32 need a voltage divider.

Features:

• Measuring range 0 to 1.2 MPa, overload up to 2.4 MPa
• Analogue output 0.5 to 4.5 V with 5 V supply
• Stainless steel housing with G1/4 pipe thread
• For clean, non-corrosive liquids and gases

Application Examples:

• Monitoring water pressure in the domestic installation or irrigation
• Controlling a pump depending on pressure
• Measuring pressure in compressed air systems up to 1.2 MPa
• Integration into Home Assistant with ESPHome
