The T3551 is a digital LUX level Zig 2.4 GHz Wireless Mesh Network sensor that is factory calibrated and used to report the luminance in work places and similar environments. Calibration data is stored within the sensor.
- Battery based (2x AA)
- The T3551 is able to measure LUX levels between 1 to 150,000 LUX with accuracy as good as ±1% within calibrated levels typically between 1 and 2,000 LUX. Higher LUX levels
have a degrading level of accuracy, typically between ±1% and ±5%.
- The LUX level sampling periods are every second for ½ a mains 50Hz cycle. These readings are then used to create an averaged LUX level transaction every Zig 2.4 GHz Wireless Mesh Network reporting period, typically each minute.
- The sensor electronics operate in an inherently linear mode and has two gain ranges that are either user or auto selected. These are the high gain mode between 1 and 2,000 LUX and the low gain mode between 100 and 150,000 LUX.
- Low battery alert
