How to Make an IR Sensor -

· We can use an IR sensor module built into this project as an obstacle sensor instead of ultrasonic sensor. In this project, you are going to learn how to build obstacle sensor using transistor (for those who doesn't know about arduino) and using an Arduino as well. For learning how to use ultrasonic sensor to make distance measurement using ...

How do you get a temperature sensor from a transistor?

· As an integral aspect of the transistor’s defining equations, the temperature sensitivity of the PN junction is quite predictable and very linear over the typical semiconductor operating range of -55 to +150°C. In addition to a PN junction in a diode, a semiconductor junction temperature sensor can be achieved by short circuiting the collector-base junction of a bipolar transistor to create ...

Infrared Sensor - How it Works, Types, Applications ...

IR sensor is a simple electronic device which emits and detects IR radiation in order to find out certain objects/obstacles in its range. Some of its features are heat and motion sensing. IR sensors use infrared radiation of wavelength between to 1000µm which falls between visible and microwave regions of electromagnetic spectrum. IR region is not visible to human eyes. Infrared spectrum ...

IR Transmitter and Receiver Circuit Diagram

· We have use BC557 PNP transistor here, to reverse the effect of TSOP, means whenever the output is HIGH LED will be OFF and whenever it detects IR and output is low, LED will be ON. PNP transistor behaves opposite to the NPN transistor, it acts as open switch when a voltage applied to its base and acts as closed switch when there is no voltage at its base. So normally TSOP output …
