Here is the simple Arduino and 3 Ultrasonic sensor based Human-following robot code that you can use for your project. The MAX_DISTANCE and MIN_DISTANCE_BACK variables set the thresholds for obstacle ...

They are often referred to as PIR, “Passive Infrared”, “Pyroelectric” or “IR motion” sensor. Since it costs ... author’s prototype of the human detector Now it’s time to Rock and Roll. Open your ...

Abstract: Human detection using sensors preserves the privacy. The Passive Infrared (PIR) sensor is used to detect the presence of human. But this detects the human only if they are in motion.

The Arduino TCS3200 sensor is a reliable currency detector that accurately detects and identifies various currencies based on their unique color patterns, making it an essential tool for automated ...

By using this formula you can convert any analog voltage to t Arduino analog read value. The below circuit diagram shows you the circuit connections for the Rain Drop Sensor with Arduino. The design ...

He suspected EMF interference so as a quick first step he decided to throw together an EMF detector using an Arduino. It uses a bank of LEDs as an indicator bar to reflect the EMF picked up by the ...

Maintaining a distance of 1.5 meters between the sensor and the chest, with proper alignment to the detection area, ensures accurate monitoring of breathing and heartbeat data. The Seeed Studio 60GHz ...

This is a simple color sensor using Arduino Uno R3 and TCS3200 color sensor module. It can be useful for color identification and detection for food-processing units, color printer applications, paint ...

This detector circuit uses just the Arduino Nano itself, no added sensor. Blowing some air from 30cm distance can be detected. It detects via measuring the internal heated chip temperature with 0.01 ...
