M5Stack AIN 4–20 mA (U162) – input for industrial sensors

Many industrial sensors, such as tank level sensors, pressure sensors and flow meters, send their value as a current of 4–20 mA. This unit reads the current in an isolated way and gives you the value over I2C.

Works with

• Arduino and UIFlow
• ESPHome via custom I2C code (no built-in support)
• All M5Stack controllers with a Grove port

You also need

A controller and a 4–20 mA sensor. Grove cable included.

Specifications

• Input: 1 channel 4–20 mA, isolated
• Sensor supply: internal or external (jumper)
• Interface: I2C via Grove, address 0x55
• Size: 56 × 24 × 11.3 mm
