Ultrasonic sensor is a device that can measure the distance to an object by using sound waves. It measures distance by sending out a sound wave at a specific frequency and listening for that sound wave to bounce back. By recording the elapsed time between the sound wave being generated and the sound wave bouncing back, it's possible to calculate the...
IR Multipurpose Sensor. Widely used for line follower and obstacle sensing robot for black and white line and object. 5V operated, easy to interface with wide range of microcontroller. Like ARDUINO,AVR,ARM,8051,PIC,MSP430 etc. Sensing range is adjustable with inbuilt variable resistor. , Digital output.
LM35 is a precision IC temperature sensor with its output proportional to the temperature (in oC). LM35, temperature can be measured more accurately than with a thermistor. It also possess low self heating and does not cause more than 0.1 oC temperature rise in still air.The operating temperature range is from -55°C to 150°C.
The TSOP 1738 is a member of IR remote control receiver series. This IR sensor module consists of a PIN diode and a pre amplifier which are embedded into a single package. The output of TSOP is active low and it gives +5V in off state. When IR waves, from a source, with a centre frequency of 38 kHz incident on it, its output goes low.
