Kit contents: , 1x pir sensor, 1x ir sensor, 1x dht11 sensor/ module, 1x sound sensor. , 1x joystick module. Description: Bracket sensor bracket fixture intelligent car supporting height adjustable without screws winder fixed blue circuit board hc-sr04. Shipping list:1pcs x hc-sr04 sensor and 1pcs bracket. Pir:Pir infrared sensor module is based on infrared technology, automatic control products. High sensitivity, high reliability, low power consumption, low voltage operation mode. Widely used in various auto-sensing electrical equipment, especially for battery-powered automatic control products. Ir: This is an infrared based proximity sensor which is great for obstacle avoidance and line following robots. Our infrared transceiver module contains an infrared transmitter and a receiver fit in a compact form on a tiny board. Transmitter emits infrared light and another receiver (photo-transistor) receives that ir light after reflection. The module can be used to identify an obstacle or a nearest object dht11:Dht11 digital temperature and humidity sensor module is a composite sensor contains a calibrated digital signal output of the temperature and humidity. The application of dedicated digital modules collection technology and the temperature and humidity sensing technology is to ensure that the product has high reliability and excellent long-term stability soundsensor:2 outputs, analog output and real-time microphone volt. Joystick module biaxial keys use corporation ps2 gamepad buttons on the original high-quality metal rocker potentiometer, analog output module and one ad hoc road digital output interface, the output value corresponding to (x, y) pairs axis offset which is of analog type, coordinate identifiers clear, concise, accurate positioning.
