Low power BLE enabled CO2 and NO2 gas monitoring device. Beside the gas level monitoring device allows for ambient temperature monitoring and setting the thresholds for all sensors to generate alarm notifications. Device BLE interface is activated through the predefined period time (for mobile phone to achieve connection) through the simple shake of the device.
Requirements:
- BLE interface for device configuration,
- CO2, NO2 and temperature monitoring,
- Motion detection
- Audio signal for out of range indication
- Small and compact size
Major components:
- nRF51822 BLE SoC
- MCP6042 & ECS1, COZIR
- ADXL362
- PCF8563
- TPS61220
Number of PCB layers : 4
Realization time: 8 weeks
BOM price: 177 USD
