Smarter home

Product code: MCCGQ02HL Dimensions: 34.0 x 32.7 x 14.5mm Operation temperature: -10C ~ 50C 0%-95%RH Connection: Bluetooth 5.1BLE Battery: CR2032  This new Mi sensor is a bit different than the older Mi door and window sensor. In the first appearance you can see that it is a bit bigger. There are a few reasons for that: one is that it uses a more available battery: CR2032 and not the CR1632 in the older version. The other reason is that it also has a light sensor where it can detect bright and dim situations. The old version connects through Zigbee while this one connects through Bluetooth Low Energy. To use this in your home automation setup you will need a Bluetooth enabled hub like the newer Mi home hub 3 (ZNDMWG03LM).  It has on top of the normal open/close notifications a couple of schemes like "alert after x seconds open/closed".

Model number: gzcgq01lm Product size: 41 × 41 × 15mm Wireless connection: Zigbee 3.0 Sensitivity range:  0 ~ 83000 lux Battery model: CR2450 Operating temperature: -10 ℃ to -50 ℃  0% -95% RH This light sensor will measure the light intensity from 0 to 83000 lux. The range is adequate to measure full darkness (0 lux), sunset/sunrise (40-400 lux), overcast daytime (1000-2000 lux), and a sunny day (110000 lux). In the sensor are two magnets so you can stick it to any metal surface. Because this sensor uses the zigbee 3.0 protocol it will only work on the newer Mi home hubs like the ZNDMWG03LM.
