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.

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.

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.

Ranges from 20cm up to 765cm* with a 10Hz read rate. Analog envelope, analog voltage, and RS232 serial. Reports range to largest target. Uses a stability filter.

Discover the MB7389 ultrasonic sensor with IP67 rating for reliable bin level detection. Engineered and assembled in the USA. Shop now at MaxBotix.

Ultrasonic vehicle detection sensor for drive-thru lanes, gates, and parking garages. 5 m maximum range, 1 cm resolution, and ~250 ms between readings (~4 Hz), plus a preset 1.5 m proximity zone.

Near-field handling is built in: objects closer than 50 cm are reported as 50 cm for predictable behavior.

Interface is selected at purchase: Micro USB, TTL, or RS232. 

MB7851 is a weather-resistant ultrasonic tank-level sensor with 1 mm resolution, 5 m max range, and ~2 Hz read rate. Output is selectable by wiring—RS232 or TTL serial, scaled analog voltage, or analog envelope; supply 3.0–5.5 VDC

Near-field handling is built in: targets closer than 50 mm are reported as 50 mm for predictable readings.

(Optional at purchase: 4–20 mA; requires 9–36 VDC and replaces standard outputs). 

This ultrasonic sensor provides range information from 20cm up to 765cm* for the nearest detectable target at 1-centimeter resolution with a speed of 10Hz, and pulse-width, analog voltage, and RS232 serial outputs.

Ranges from 6 inches to 125 inches. 5-foot detection zone for proximity information with a ~2.5-second acquire time and ~1.5-second release time.

Ranges from 20cm to 765cm with up to 40Hz read rate. Narrow detection field. High noise tolerance.

The Flood Level Ultrasonic Sensor provides highly accurate non-contact measurement for flood detection and water level monitoring. With 1 mm resolution and models available in 5 m and 10 m max ranges, this sensor is designed for reliable operation in stormwater, municipal, and environmental monitoring applications.

Near-field handling is built in: targets closer than minimum range are reported as minimum range for predictable readings (300mm on 5m models and 500mm on 10m models.)

(Optional at purchase: 4–20 mA; requires 9–36 VDC and replaces standard outputs).

Ranges from 20cm to 1068cm with a 10Hz read rate. Analog envelope, analog voltage, and RS232 serial. Reports range to closest target.

Ranges from 6 inches to 125 inches. 3-foot detection zone for proximity information with a ~2.5-second acquire time and ~1.5-second release time.

Ranges from 300mm to 5000mm with a ~4Hz read rate. Widest detection field. Excellent for people detection.

Ranges from 20cm to 350cm with a 6.7Hz read rate. Pulse-width, analog voltage, and RS232 serial. Reports range to largest.

Ranges from 6 inches to 125 inches. 1-foot detection zone for proximity information with a ~2.5-second acquire time and ~1.5-second release time.

Ranges from 300mm to 5000mm with a ~4Hz read rate. Narrowest detection field. Highest noise tolerance.

Ranges from 6 inches to 125 inches. 2-foot detection zone for proximity information with a ~2.5-second acquire time and ~1.5-second release time.

Ranges from 300mm to 5000mm with a ~4Hz read rate. Mid-width detection field. Balance between sensitivity and side object detection.

Ranges from 300mm to 5000mm with a ~4Hz read rate. Wide detection field. Excellent for people detection.
