Sensor Node

Exilight – Wireless Sensor Node

Sensor Node is packed with a variety of sensors to monitor indoor environmental quality. It keeps track of air quality index (via measuring a broad range of gases including Volatile Organic Compounds), temperature, humidity, ambient light, noise and barometric pressure.

Sensor Node runs Wirepas Mesh connectivity software making it the perfect for large-scale mesh-networks for sensor data collection. Product is integrated EXIoT, MS Azure.

Air quality (VOC)

Detects a broad range of gases to measure air quality, including Volatile Organic Compounds.

Ambient noise

Approximate to human-ear noise range, output in dB. Acoustic sensor, a low noise input buffer and an output amplifier. Omnidirectional with RF immunity.


High-precision temperature sensor.
Sensor accuracy, max +/- 0.2 °C.

Ambient light

Approximate the human-eye response.
High accuracy requires a direct line of sight to
sensor (on the right side of the node button).


Magnet proximity binary detection.
