Waterproof Ultrasonic Ranging Module Dual Probe Ranging JSN-SR04T :
$11.52

The JSN-SR20-Y1 dual-probe ranging module can provide a non-contact distance sensing function of 2cm-500cm, and the ranging accuracy can reach as high as 3mm; the module includes a transceiver integrated ultrasonic sensor and a control circuit. The usage of mode one is similar to our HC-SR04 module.


This product adopts industrial-grade dual waterproof ultrasonic probe design, waterproof type, stable performance, and humility to work with all MCUs on the market.


Super close range, the blind zone is only 2CM. Stable ranging is a powerful basis for this product to successfully enter the market.


Features:


1. Small size and convenient to use;


2. Ultra-small blind area measurement.


3. High measurement accuracy;


4. Strong anti-interference;


5. Integrated enclosed waterproof tape probe, suitable for wet and harsh measurement occasions

mode 0:Moode = open that is no welding. The mode as follows

1, basic working principle:

(1)use IO port TRIG to trigger ranging, and present high-power level signals with a minimum of 20US.

(2)the module automatically sends 8 square waves of 40kHz to automatically detect whether there is a signal return;

(3)if there is a signal, ECHO outputs a high level through the IO port. The duration of the high level is the time when the ultrasonic wave returns from sending it. Test distance = (high level Time * sound velocity (348M/S))/2;

(4) after the module is triggered for distance measurement, if no ECHO is received (the reason is beyond the measured range or the probe does not face the measured object), the ECHO Port will automatically become low after 40ms, marks the end of this measurement, whether successful or not.
