Medical First Aid Training, Institute of Advanced Security Management. The initial stages of the electronic security market in India were marked by a profusion of vendors and service providers, a none-too-aware market and a lack of awareness among customers. Recent years have seen a more ‘serious' electronic security market coming into view in India. While the crowd of manufacturers is still seen, especially in the lower end of the market, the entry of international players in the market, either through local companies, tie-ups or imports has given it a more organized feel. As there is no formal education on electronic security, getting trained man power is an uphill task and also for the working brigade to hone their skills time to time is pretty difficult, we have formulated courses catering to the growing requirements of the electronic security industry.

Arduino - HomePage. Parallax Inc | Equip your genius ® PIR Motion Sensor. The PIR Sensor Rev B can tell when something nearby moves. The sensor detects the pattern of infrared energy in its surroundings. If the pattern changes, the sensor outputs a high signal. The Propeller microcontroller only needs to monitor this signal with an I/O pin to know if something is moving around nearby. Parts (1) PIR Sensor Rev B (#555-28027)(1) 220 ohm resistor(3) jumper wires The PIR sensor connects to 3.3 V, ground and a single Propeller microcontroller I/O pin. (The 220 ohm resistor isn’t strictly necessary, but it could help protect the sensor from an accidental signal sent from the Propeller I/O pin, which could happen from wiring or coding errors.)
Turn off power to your board’s prototyping area (PWR switch to 0 for the Activity Board).Connect your PIR Rev B to your Activity Board as shown below. The following program continuously checks and prints the output state of the PIR sensor. The code is entirely inside an infinite while(1) loop. What’s that glow?
