Description

The JSN-SR04T is an ultrasonic distance measuring module that is waterproof, making it suitable for various outdoor or wet conditions where standard ultrasonic modules may fail. It's a popular sensor for applications like robotics, vehicle detection, water level monitoring, tank level tracking and more.

Key Features
Waterproof: Suitable for outdoor applications and in wet conditions.
Measuring Range: 20cm - 600cm.
Working Voltage: 3-5.5V DC.
Working Frequency: Around 40kHz.
Accuracy: 2mm.
Working Temperature: -10 to 70 degrees Celsius.

Connections
VCC: Connect to 5V power supply
GND: Connect to the ground
Trig: Trigger input pin
Echo: Echo output pin

Usage
To use the JSN-SR04T, you trigger a high-level pulse for at least 10 microseconds on the 'Trig' pin. The module will send out an ultrasonic wave, and if an object is within range, the wave will bounce back to the sensor. The module then outputs a high-level pulse on the 'Echo' pin. The duration of this pulse is proportional to the distance to the object. Great for Arduino sensor projects.
