Let's take a closer look at the BlitzWolf® Smart Home Door Sensor.
This product also known as the BW-IS6 Tuya 433MHz Door & Window Sensor, is designed to provide real-time app push alarms for smart home security systems.

One of the most unique aspects of this door sensor is its sensing distance of over 1.5cm. It operates on a cell battery CR2032 and has a standby current of only 8μA. The alert current is less than 15mA making it an energy-efficient device that won't drain your battery quickly. The self-adhesive pads make it easy to fit, and its small size makes it discreet when installed on doors or windows.
