WSLRW-AL is a LoRaWAN ambient light sensor with built-in the ultra low power light sensor that measures the intensity of visible light. The spectral response of the sensor tightly matches the photopic response of the human eye and includes significant infrared rejection. The precision spectral response and strong IR rejection of the device enables the AL sensor to accurately meter the intensity of light as seen by the human eye regardless of light source. Measurements can be made from 0.01 lux up to 83k lux without manually selecting full-scale ranges by using the built-in, full-scale setting feature. This capability allows light measurement over a 23-bit effective dynamic range. Ultra-low-power design and smart firmware allow the sensor to run on a 2 x AA battery 1.5V for 10 years with one update per day. It can support all frequency regions in over the World. The sensor will transmit data in kilo-meters distance to the LoRaWAN gateway, any brand on the market.
For Applications
Facility Monitoring, Safety Monitoring
LoRaWAN communication
LoRaWAN communication standard to allow sensor connect to any LoRaWAN Gateway on the market.
10-Year battery
Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology allow the sensor can last up to 10 years with 02 x Type AA batteries.
