Infrared sensor tube and Radar sendor tube difference

1. Working principle

Microwave radar sensor LED light, also known as radar sensor LED light, is a new type of intelligent lighting product based on the Doppler effect, using the most advanced planar antenna, and automatically controlling the light source to lit up through the sensor module;

The infrared sensor lamp is designed with imported technology MCU circuit, active infrared working mode, with infrared decoding mode.

2. Performance

The sensing distance of the microwave radar LED light can reach 8-10m. It can effectively suppress the interference of high-order harmonics and other clutter, with high sensitivity, strong reliability, safety and convenience, and it is energy saving; microwave induction dimming lamp has a longer sensing distance, wide angle, no dead zone, and can penetrate glass and thin wood, depending on the power, can penetrate walls of different thicknesses.

The sensing distance of infrared sensor LED light is generally 3-5m. It has the characteristics of good stability, strong anti-interference, and energy saving. However, the sensing distance is easily affected by external environmental factors such as temperature and dust. The sensing distance in summer may be only 1-3m.

3. Installation method of the sensor

According to the characteristics of radar sensing technology, it can penetrate non-metal objects, so the sensor of the microwave radar led lamp can be built into the lamp;

The infrared sensor lamp must expose the human body sensor receiver outside the lamp to collect the infrared energy change of the environment.

4. Cost

Due to chip cost issues, the price of infrared sensor modules is higher than that of radar sensor modules.
