PIR-Sensor mit Transistor

Overview | PIR Motion Sensor | Adafruit Learning System

20140128· Along with the pyroelectic sensor is a bunch of supporting circuitry, resistors and capacitors. It seems that most small hobbyist sensors use the BISS0001 ("Micro Power PIR Motion Detector IC"), undoubtedly a very inexpensive chip takes the output of the sensor and does some minor processing on it to emit a digital output pulse from the analog sensor.

How to Connect a Transistor as a Switch in a Circuit

Since the PIR motion sensor outputs current and the transistor is a switch that turns on by electrical current, it''s a perfect switch that works complementary with the transistor. A mechanical switch is when a human needs to press down to operate it. A transistor is when an electrical current switches something on. So, again, transistors are used when we want electrical current to control the ...

How PIRs Work | PIR Motion Sensor | Adafruit Learning System

20140128· There is actually a JFET inside (a type of transistor) which is very lownoise and buffers the extremely high impedence of the sensors into something a lowcost chip (like the BIS0001) can sense. Lenses PIR sensors are rather generic and for the most part vary only in price and sensitivity. Most of the real magic happens with the optics. This is a pretty good idea for manufacturing: the PIR ...

20200209· I am using a PIR sensor, a LDR along with a transistor. I have included a resistor in the output from the PIR to the base of the transistor. The LDR ties the base of the transistor to ground. The size of this resistor increases the amount of darkness before lighting the led. This of course reduces the signal to the base of the transistor which causes the transistor not to fully saturate and ...
