PIR Sensor - remove the 'delay' when detecting motion ...

· Howdy, I have a PIR sensor and simply want to have a green LED light up when there's motion detected, otherwise have a red LED light up. I have that part working, no problemo. However, it seems that when I move my hand in front of the sensor, and then move it away, the PIR still thinks the motion is there for a slight delay (a second maybe).

Advanced Motion Detector Using PIR Sensors Reference ...

Advanced Motion Detector Using PIR Sensors Reference Design For False Trigger Avoidance The low current consumption of only 75 nA (typical) per comparator makes the TLV3691 in this TI Design ideal. Other considerations for the comparator in this reference design include its low input voltage offset and low input bias current. Additionally, the TLV3691 features a rail-to-rail input stage with ...

What is a PIR Motion Sensor: PIR IC Working, Features and ...

Supply Voltage – 5V. Delay Time Adjustable. Standard TTL Output. PIR Sensor IC . The PIR sensor IC consists of 3 pins- Vcc, Ground and Output. In presence of human IR radiations, the sensor detects the radiations and converts it directly to electrical pulses, which is fed to the inverter circuit. The inverter circuit consists of a transistor,which gets into saturation with application of ...

Convert a 5v PIR Motion Sensor to for ESP8266 ...

In my tests the HC-SR501 PIR Motion Infrared Sensor falsed when I attempted to use volts at the VCC input pin. Luckily there is a simple solution to get the Motion Sensor to work with volts boards like the ESP8266. UPDATE!!! Thanks to Dosman71 - I originally said to solder to the middle terminal of the onboard regulator, This is WRONG!!
