ALSRobotBase PIR Sensor for Arduino

Descripción

Description:The PIR (Passive Infra-Red) Sensor is a pyroelectric device that detects motion by measuring changes in the infrared (heat) levels emitted by surrounding objects. When motion is detected the PIR Sensor outputs a high signal on its output pin. This logic signal can be read by a microcontroller or used to drive an external load. Dual output modes and a sensible design that performs within stated datasheet specifications are a few reasons over 100,000 units are in use around the world.Specification:Power requirements: 3 to 6 VDC; 130 ¦ÌA idle, 23 mA active (no load)Communication: Single bit high/low outputDimensions: 1.41 x 1.0 x 0.8 in (35.8 x 25.4 ?x 20.3 cm)Operating temp range: 32 to 122 ¡ãF (0 to 50 ¡ãC)Weight: 8g
