Item Description:
1pcs Ultra Module HC-SR04 Distance Measuring Transducer Sensor For Arduino
Specification
2)Static current: less than 2mA
3)Ou t signal: Electric frequency signal, high level 5V, low level 0V.
4)Sensor angle: not more than 15 degrees
5)Detection distance: 2cm-450cm
6) High precision: up to 0.3cm
7) Input trigger signal: 10us TTL impulse
8) Echo signal : ou t TTL PWL signal
9) Connection:
VCC,
trig (control side),
echo (receiving end),
GND
Usage:
10US a control population of more than a high-fat, you can wait to receive high ou t port. A timer can be opened with the ou t timing, when the port goes low when the timer value can be read this when the time for this distance, only calculate the distance. This constant cycle of measurement, you can reach the value of the mobile measurement ~ ~
Module works:
The IO trigger location, the high signal to at least 10us;
The module automatically sends eight 40khz square wave, automatically detects whether a signal
