MOC 3021 Circuit

[the_ad id=”10894″]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. Forward Peak current =1A. 4. Max power =200W. 5.

How to use PIR Sensor?

Passive InfraRed (PIR), PIRs are basically made of a pyroelectric sensor, which can detect levels of infrared radiation. Everything emits some low level radiation, and the hotter something is, the more radiation is emitted. The sensor will under typical conditions, detect a human being moving around within

MAX232 Pin Details

The MAX232 is a dual driver/receiver that includes a capacitive voltage generator to supply MAX-232 voltage levels from a single 5-V supply. Each receiver converts MAX232 inputs to 5-Voltage TTL / CMOS levels. These receivers have a typical threshold of 1.3 V, a typical hysteresis of 0.5
