Sensor Development

The use of wireless sensor technology has significant potential benefits for infrastructure monitoring, allowing a rapid deployment due to the elimination of cabling. Combined with low power Micro Electro Mechanical Systems (MEMS) sensors, there is an opportunity for substantial overall cost savings for large-scale monitoring.

The developed prototype sensor consists of a methane flux chamber including

• Microcontroller (ESP32 with LTE modem)
• Non-dispersive infrared Methane sensor (0-50,000 ppm range)
• Three functional sensor to measure Temperature, Barometric Pressure, and Humidity

Enabling the following features

• Data transmission to IoT server (Real-time and every second)
• Fully-autonomous and Solar self-powered
• Collect continuous and diurnal methane emission data, which can analyze seasonality of surface methane emission
