The ST-04BL is an alarm device designed for applications such as fire detection, intruder alert and fall detection. It is an active type of alarm, meaning that it sends out a loud siren when it is activated. The ST-04BL has a built-in photoresistor and comes with two settings; one for detecting motion or vibration and another for detecting light.When the ST-04BL is activated, it sends out an alarm signal in the form of a loud siren. This signal is audible up to 200 feet away. The siren can be easily set off by a motion or light sensor, which makes it ideal for applications such as intruder alert and fire detection.The ST-04BL works by using aphotoresistor to detect light, and an accelerometer to detect motion or vibration. When either of these conditions is detected, the ST-04BL sends out an alarm signal in the form of a loud siren. The ST-04BL can be set up in a variety of alarm configurations, allowing it to be customized for different applications. For example, if the device is used for intruder alert, the sensitivity of the motion sensor can be adjusted so that only large movements are detected. In addition, the ST-04BL is powered by a 9-volt battery, giving it a long battery life. It also has a low-power mode, allowing it to conserve battery life when not in use. The ST-04BL is an ideal alarm system for applications such as fire detection, intruder alert and fall detection. Its loud siren and adjustable settings make it a convenient and reliable choice.
