MOC 3021 Circuit Working Principle

MOC 3021 Circuit The MOC302X (MOC3020,MOC3021,MOC3022 are same) series are mainly coupled as a isolators consist of a infrared LED with light activated SCR. DRIVE CAPACITY: 1. Off state output voltage = 400V. 2. RMS Forward current = 100mA. 3.…

IR sensor Working Principle and Applications

IR sensor Working Principle and Applications The sensor is a transducer type, it is used to sense or detect events or changes in physical quantities and gives a corresponding analog output. TYPES OF SENSOR: 1. IR sensor. 2. proximity sensor.…

Temperature Sensor LM35 and its Applications

Temperature Sensor LM35 The LM35 series are precision integrated-circuit temperature sensors, whose output voltage is linearly proportional to the Celsius (Centigrade) temperature. The LM35 thus has an advantage over linear temperature sensors calibrated in ° Kelvin, as the user is…
