MTP40-F NDIR CO2 sensor

Small CO2 sensor. Works on NDIR principle and provides readings in range of 400-5000 ppm. MTP-40F is compatible in basic pinout with Winsen MH-Z1311A, so You can use PCB adapter to also with MTP40-F. But UART protocol is different than used by Winsen.

Accuracy - ±(50 ppm + 5% of reading value).

Specification:

• Power supply: 4.2-5.5V
• Current consumption - 300 mA in peak, 13 mA average (provide good power supply)
• UART and I2C interfaces (I2C only for readings, configuration only via UART)
• UART is not 5V tolerant, use logic level converter when interfacing with µc with TTL 5V (most Arduinos)
• Additional PWM and Alarm output
• Self calibration after 24h, then every 7 days
