ULTRASONIC SENSOR MODULE AVAILABLE IN DELHI !! IN INDIA

Ultrasonic Module HC-SR04 Distance Measuring Transducer Sensor The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). Ultrasonic Ranging Module HC-SR04 provides 2cm-300cm non-contact distance sensing capabilities,Ranging accuracy up to 3mm; module comprises an ultrasonic transmitter, a receiver and a control circuit. Module 's main technical parameters: 1. Working Voltage: 5V(DC) 2. Static current: Less than 2mA. 3. Output signal: Electric frequency signal, high level 5V, low level 0V. 4.
