Object motion detector circuit diagram
The core component of the motion detection circuit is the motion detection chip IC1 (KC778B). The signal frequency from the PIR sensor is low, ranging from 0.1Hz to 10Hz, while the bandwidth is quite broad, which the chip will optimize....
Proximity Alarm
Inverters U1a and U1b are connected in a simple RC oscillator circuit. The frequency is determined by the values of R1, C1, C2 and the internal characteristics of the integrated circuit. As long as the circuit is oscillating, a positive...
Motion Detector Sensor Circuit
This circuit is a motion detection sensor that utilizes a light source and detector as an infrared motion detector. It incorporates components such as a light-emitting diode (LED), a phototransistor, a transmitter, a receiver, an NE555 timer configured as an...
Optical schmitt trigger
This circuit illustrates a 555 timer with its trigger and threshold inputs connected together, which is utilized to activate a relay when the light level detected by a photoconductive cell drops below a predetermined threshold. Additionally, this circuit can be...
Scoobas Solution Sensing Tactic
This document serves multiple purposes, primarily to document the methods employed by a Scooba robot to detect: a) the presence of an acceptable cleaning solution being delivered to its pump, and b) the excess presence of used solution collected off...
Wire Break Sensor Alarm Circuit Schematic
The circuit of a loop sensor-based simple security alarm is described here. The sensor loop consists of a short length of thin enamelled copper wire.
The loop sensor security alarm operates on the principle of detecting interruptions in the circuit formed...
Motion Activated Camera
A straightforward attachment for a Canon SLR camera designed to create a motion-activated camera using an Arduino. This project draws inspiration from the intervalometer project at The Honey Jar, with modifications made to the circuit by utilizing a 4N35 optocoupler...
Optical Proximity Detector Circuit
A reflector isolator detects the presence of an object by bouncing light off of it. This technique is useful in circuits that detect when an object is close enough to the sensor.
A reflector isolator is a type of optical sensor...
Electronic Watchdog
The electronic watchdog circuit functions similarly to a traditional guard dog, monitoring a 10-meter area around a door. When someone enters this monitored zone, the circuit emits a realistic barking sound. This sound can be sustained for 10 seconds, and...
