The RF433 Wireless Glass Break Sensor is a reliable solution for protecting your home or office,
designed to detect glass breakage through precise acoustic analysis. Equipped with a microprocessor
8/12 bit digital (8MHz) and digital filters for RFI/EMI, ensures high sensitivity with minimal
possibility of false alarms. This device detects only the distinctive sounds of glass shattering,
protecting windows , doors and glass effectively. This device integrates easily with systems
GSM or WiFi alarm based on RF433 protocol, ensuring immediate protection against intrusions.
The sensor uses a highly sensitive microphone that can identify the characteristic sounds of glass breaking.
Its analysis is based on a digital detection system that processes seven different audio frequencies,
accurately distinguishing the sounds of shattering glass from other ambient sounds. This technology
helps prevent false alarms caused by random noises such as wind, pets or traffic.
The device is equipped with a sensitivity adjustment function , which allows you to adapt the sensor to different
environments. With the sensitivity set to maximum , the sensor can cover an area of up to 9 meters .
In low sensitivity mode, coverage drops to 4.5 meters, making it ideal for smaller rooms.
or for monitoring individual windows . Adjustment is done manually, using the
Yellow LED indicating the noise level detected during calibration.
The sensor operates on the RF433 MHz frequency, which makes it compatible with most alarm control panels.
Tuya and with GSM or WiFi systems that support this frequency. The device immediately sends a signal
alarm to the central unit when it detects glass breakage, activating Sirens or notifications via the alarm control unit.
The glass break sensor offers a wireless transmission range of up to 100 meters in open field , ensuring
stable communication with the alarm control panel , even in large environments or structures with multiple rooms.
The sensor is equipped with an anti-tamper function that prevents attempts at deactivation or sabotage. Any
Any attempt to open or disconnect the sensor immediately activates the alarm , increasing the security level of the system.
The sensor is quick to install and does not require complex interventions. It can be mounted on walls, ceilings or in proximity
of windows and glass doors . The device is powered by DC 12V and can be installed wired or wirelessly,
as needed. Using a power cord ensures consistent and reliable performance.
The sensor is equipped with LED indicators that provide visual feedback on the status of the device.
The yellow LED flashes when detecting noise and signals the sensitivity level during calibration.
The red LED illuminates when the alarm is activated , providing a clear visual indication of activation.
