Ultrasonic Sensor User Guide
HC-SR04 User Guide 1. Ultrasonic Distance Measurement Principles The transmitter emits a 8 bursts of an directional 40KHz ultrasonic wave when triggered and starts a timer. Ultrasonic pulses travel outward until they encounter an object, The object causes the the wave to be reflected back towards the unit. The ultrasonic receiver would detect the reflected wave and stop the stop timer. The velocity of the ultrasonic burst is 340m/sec. in air. Based on the number of counts by the timer, the distance can be calculated between the object and transmitter The TRD Measurement formula is expressed as: D = C X T which is know as the time/rate/distance measurement formula where D is the measured dist...

IR motion sensor
HC-SR501 IR датчик движения Инфракрасный датчик движения HC-SR501 предназначен для обнаружения движущихся обьектов на расстоянии от 3-х до 7 метров. Содержит встроенный таймер от 5 до 300сек, и регулировку дальности обнаружения. При срабатывании вырабатывается положительный сигнал на выходе «OUT» (3,3в), который подается на исполнительное устройство ( в комплект не входит). Режим работы устройства задается перемычкой J1. Устройство содержит защиту от переполюсовки по питанию, а также возможность подключения дополнительного фоторезистора. ОСНОВНЫЕ ХАРАКТЕРИСТИКИ - Дальность обнаружения до - Питание: - Время работы таймера: - Нагрузочная способность выхода: - Рабочая температура: 7м 4,5В ...

PIR Sensor
PIR Sensor (HC-SR501) Introduction Passive Infra-Red (PIR) sensors are used to detect motion based on the infrared heat in the surrounding area. This makes them a popular choice when building a system to detect potential intruders or people in general. These sensors can take for 10-60 seconds to warm up, so try to avoid motion during that time. Parts • • • Arduino PIR Sensor Wires Schematic Below is the schematic for using a PIR sensor. It is fairly simple. Code Adafruit has a really good tutorial for how these sensors are used and various projects for them. Below is the code for working with a PIR sensor. It should be noted that the PIR sensor does not respond immediately when motion s...
