WSLRW-O2 is the Wireless Ambient Oxygen Sensor, it utilizes a galvanic cell type oxygen sensor that provides a linear output voltage signal relative to the percent oxygen present in a particular atmosphere. The sensor features no position dependency, excellent chemical durability, and it is not influenced by CO. With Ultra-low Power design and smart firmware allow the sensor can last up to 10 years with 02 x AA-type battery (depends on configuration). The sensor will transmit data in kilo-meters distance to LoRaWAN gateway, any brand on the market. There are a lot of applications as environment monitoring for office, hospital, cleanroom, agriculture, food warehouse...
For Applications
Ambient Air Quality Monitor, Indoor Air Quality Monitor, Gas Analyzing, Warehouse Monitoring
LoRaWAN communication
LoRaWAN communication standard to allow sensor connect to any LoRaWAN Gateway on the market
Not affected by other gases
Virtually no influence from CO2, CO, H2S, NO, H2 (Version O2-02)
5-10 years battery
Ultra-low power sensing technology from Daviteq with Ultra-low power wireless technology allows the sensor can last up to 5-10 years with 02 x AA batteries
