: This performance of the ultrasonic sensor distance measuring module is stable, measure the distance accurately. The module is with High precision, blind spots (3cm) super close. This module provides a full set of ranging process. - Model: HC-SR04 - Color: Blue + Silver - Working voltage : 5V(DC) - Static current: Less than 2mA. - Output signal: Electric frequency signal, high level 5V, low level 0V. - Sensor angle: Not more than 15 degrees. - Detection distance: 2cm~450cm. - High precision: Up to 3mm - Mode of connection: VCC / trig(T) / echo(R) / GND - Module Working Principle: - Adopt IO trigger through supplying at least 10us sequence of high level signal - The module automatically send eight 40khz square wave and automatically detect whether receive the returning pulse signal - If there is signals returning, through outputting high level and the time of high level continuing is the time of that from the ultrasonic transmitting to receiving Dimensions: 1.26 in x 0.94 in x 0.98 in (3.2 cm x 2.4 cm x 2.5 cm) Weight: 0.21 oz (6 g)

Great for Arduino and Raspberry Pi projects. Great (and cheap) little PIR sensor. The specifications on the site are incorrect, this is a PIR sensor, not a distance measuring device. One of the potentiometers regulates sensitivity (3m to 7m) The other potentiometer...translate
