2.Suitable for Sensor Distance Measuring Module
This module has stable performance and can measure distance. Compatible with foreign SRF05, SRF02 and other ultrasonic ranging modules. The module's high precision, ultra-close blind zone (2cm), and stable ranging are a strong basis for this product to successfully enter the market.
The main technical parameters:
1. Operating voltage: DC5V 2. Quiescent current: less than 2mA
3: Level output: high 5V 4: Level output: low 0V
5: Sensing angle: no more than 15 degrees 6: Detection distance: 2cm-450cm 7: High accuracy: up to 3mm.
Wiring method, VCC, trig (control terminal), echo (receiving terminal), GND ground wire.
How to use this product: A control port sends a high level of more than 10US, and you can wait for the high level output at the receiving port.
As soon as there is output, the timer can be started. When this port becomes low level, the value of the timer can be read. At this time, it is the time of this ranging measurement, and the distance can be calculated. By continuously measuring in this way, you can You moved the measured value.
How the module works:
(1) Use IO trigger ranging and give a high-level signal of at least 10us.
(2) The module automatically sends 8 40khz square waves and automatically detects whether there is a signal returned
(3) When a signal returns, a high level is output through IO. The duration of the high level is
The time from emission to return of ultrasonic waves. Test distance = (high level time * speed of sound (340M/S))/2;
This module can provide a full set of ranging programs: C51, PIC18F877, ultrasonic LCD1602 display, ultrasonic LCD12864 display, digital tube display, serial port display, etc., ranging reference program.
