I recently purchased a Bar30 Pressure Sensor from your store, and have set about connecting it to an Arduino Mega 2560 to test the readings using the example code posted on the BR github.
Similar to this topic I am getting similar values, indicating that there is some connection issue in my circuit or a communication failure in I2C (See attached serial readout). The readings do not fluctuate as would be expected with normal sensor noise, and temperature does not respond to gentle heating of the sensor with a hair dryer.
I've attached a photo of my circuit. Connections in the 4 Pin header are soldered to the Bar30 wires. The logic level converter is shifting from 5V-3.3V correctly, here are the pin voltage diffs on the Bar30 side:
- Vin - Gnd -> 3.32V
- SCL - Gnd -> 1.78V
- SDA - Gnd -> 3.29V
Am I missing something critical, or is the sensor faulty?
