Ranges from 20cm up to 765cm* with up to a 40Hz read rate. The sensor features I2C output and reports the range to the closest target.

Ultrasonic snow depth sensor for weather stations and environmental monitoring. 5 m maximum range, 1 mm resolution, and internal temperature compensation.

Standard (~6 Hz Update Rate) or condensation self-cleaning (~0.5 Hz Update Rate) variants. RS232 or TTL serial plus analog voltage and pulse-width outputs. 

Near-field handling is built in: targets closer than 500 mm report as 500 mm for predictable readings.

MB7900 Sensor to 4-20mA Signal Converter

The MB7900 is an optional add-on for most WR and TankSensor models, enabling seamless integration with systems that require a 4-20mA output. This converter provides a 4-20mA signal through an M12 (8-pin) connection, available in both male and female connector versions, or via flying leads.

With the MB7900, there’s no need for third-party adapters, daughter boards, or additional workarounds to achieve 4-20mA compatibility—everything is built into the solution.

Note: This is not a standalone product. It must be selected as a configurable option for compatible sensors. Selecting "4-20mA" under output will automatically add the MB7900 Sensor to 4-20mA Signal Converter to the sensor's build.

The 5m Ultrasonic + IR Kiosk Proximity Sensor is a compact, low-voltage IR + ultrasonic sensor designed for kiosk and people-detection applications. By combining optical proximity sensing with ultrasonic ranging, it offers dependable object detection from the front face out to 5 m, with 1 mm resolution and range measurements from 30 cm to 5 m. 

Each sensor auto-calibrates for temperature, supply voltage, and target characteristics, delivering stable readings even in acoustically noisy indoor environments. USB and QWIIC-I2C variants simplify connection to computers and embedded systems while keeping the sensor dimensions under two cubic inches for easy mounting.
