Wireless ambient light sensor

SKU: WS433-AL

WS433-AL is a wireless ambient light sensor, using the most advanced digital technology to bring high accuracy and stable measurement. The wireless portion is Sub-GHz technology from Texas Instruments allows long range transmission at ultra-low power consumption. It will connect 2-way wirelessly to the wireless co-ordinator WS433-CL to send data and receiving the configuration. It can be configured the operation parameters like data sending interval, health check cycle...remotely from Globiots platform or via ModbusRTU software (thru the WS433-CL). Its default data rate is 50 kbps, can be switched to 625 bps to increase the communication range. The sensor can last up to 10 years with a single AA battery. And it has many applications such as continuous measurement of ambient brightness to monitor the premises or control lighting in factories, greenhouses, etc.
