Sensors encompass devices that detect and measure conditions or system events—motion, temperature, humidity, water leaks, light, door/window status and more. Choosing the right sensor means balancing detection range, accuracy, response time, power source and communications interface (wired vs wireless). Don’t overlook environmental ratings (IP, temperature extremes) and compatibility with your control or security platform. We stock passive infrared, ultrasonic, magnetic-reed, moisture and ambient-light sensors, all selected for rugged reliability in Australian conditions and seamless integration into commercial and domestic installs.
