NU40B14TR-1 40kHz Waterproof Ultrasonic Transceiver Probe

The provided specifications do not list a specific operating voltage. Typically, such ultrasonic transceiver probes require an external driver circuit for transmission and a receiver amplifier for signal conditioning. You must consult the manufacturer's datasheet or use a compatible ultrasonic sensor driver module (often 5V or 12V) to interface this probe with a microcontroller.

The 'Digital Sensor' output indicates the probe likely interfaces with a dedicated ultrasonic transceiver IC or module that provides a processed digital signal (e.g., PWM, serial). For direct connection, you typically need a driver circuit to excite the transmitter and a comparator circuit for the receiver. For easier integration, consider using it with a pre-assembled ultrasonic evaluation board that provides TTL or I2C output compatible with Arduino's digital pins.

Yes, its waterproof construction makes it suitable for outdoor or damp environments, such as rainwater tank level measurement or irrigation system monitoring. Ensure the mounting seals the enclosure properly and that the operating temperature range (-40°C to 80°C) covers your local climate conditions. For corrosive liquids, verify the housing material compatibility.
