Sub-GHz radio monitor system for CO2 using Amphenol T6713 module and ST-Microelettronics SPSGRF-868



This board designed by RSR uses the STM32L053C8 microcontroller by ST-Microelectronics to get data from Amphenol T6713 CO2 module and send it over the air via the SPSGRF-868 radio. 

The system is powered by a Li-Po rechargeable battery. The battery charger is a Qi-compliant wireless power receiver.


Amphenol T6713 NDIR CO2 module is designed for applications that require high accuracy in a compact package. All units are factory calibrated to measure CO2 concentration levels up to 5000ppm.


ST-microelectronics SPSGRF-868 is a low power sub-GHz modules based on the SPIRIT1 RF transceiver. The modules provide a complete RF platform in a tiny form factor with an air data rate from 1 to 500 kbps.
