Features:

• 23 to 600 cm (9″ to 20 feet) detection range
• 40 kHz operation
• ±37.5 degree field of view
• 2.5 meter (8′) transducer cable
• 3.3 & 5V operation and logic compatible (see notes below about 3.3V operation)

The JSN-SR04T is very similar to the standard ultrasonic modules like the HC-SR04 with the exception that it uses a single waterproof transducer instead of two and it also provides more methods for interfacing to a microcontroller.

Because the transducer is waterproof, it can be used for indoor or outdoor sensing such as providing a car parking sensor, security alarm, obstacle avoidance or monitoring the water level is water storage tanks.
