Ultrasonic Sensor Board JSN-SR04T V2.0 Waterproof Ultrasonic Module JSN-SR04T-2.0 Return Radar

describe:
The module has stable performance and accurate distance measurement. Compatible with foreign SRF05, SRF02 and other ultrasonic ranging modules
comparable. The module's high precision, blind area (25cm), and stable ranging are the powerful foundations for this product to be successfully introduced to the market.

Electrical performance:
Lead length 2.5M

Features:
1. Small size, easy to use;
2. Low voltage, low power consumption;
3. High measurement accuracy;
4. Strong anti-interference;
5. Integrated closed hose line probe, suitable for wet and harsh measurement occasions.

application:
1. Horizontal range;
2. Obstacle avoidance and automatic control;
3. The object is close and has perception
4. Traffic control;
5. Security and industrial control;
6. Artificial intelligence, teaching and research

Basic working principle:
(1) Using IOTRIGTrigger for distance measurement, at least 10us high-level signal is required;
(2) The module automatically sends 8A 40khz square wave, and automatically detects whether there is a signal return;
(3) IOECHOOutput has a signal that returns an AHigh, and the high duration is the time from ultrasonic emission to emission
Return. Test distance = (high level time * speed of sound (340M/S))/2;
This module is easy to use, a control port can be set to a high level of more than 10US, and you can wait for the high level to receive
output. An output can turn on the timer time, and the timer value can be read when the port goes low, at this time it is
The distance in time can be calculated. Such continuous cycle measurement can measure the reached value
your move.
