Panasonic Laser Particulate Matter Sensor | New Product BriefApril 29, 2020 by Mouser Electronics
This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.
Panasonic Laser Particulate Matter Sensor
Panasonic’s SN-GCJA5 Laser Particulate Matter Sensors are easy to use and provide high accuracy air quality measurements in a compact footprint. The sensors integrate an MCU, laser diode, photodiode, and micro-fan to simplify design, and uses I2C or UART to send converted mass density values to the host.
The micro-fan is more efficient at drawing in air than the heating elements used in most sensors, and the laser diode provides higher accuracy measurements than an LED-based sensor. Both the fan and laser are controlled by the MCU to extend product life and improve efficiency.
The SN-GCJA5 can detect particles as small as 0.3µm and provides a fast response.
