This is a weather-resistant Maxbotix Ultrasonic Sensor that can be used in indoor as well as outdoor conditions. The XL-TrashSonar-WR sensor series provide users with robust rang information in the air. These sensors also feature high-power acoustic output along with real-time auto-calibration for changing conditions (supply voltage sag, acoustic noise, or electrical noise), operation with the supply voltage from 3.0V to 5.5V, object detection from 0-cm to 350-cm, and sonar range information from 20-cm out to 350-cm with 1-cm resolution. Objects from 0-cm to 20-cm typically range as 20-cm. It has a read rate of 6.7Hz.
Features
Read from all 3 sensor outputs: Analog Voltage, Pulse Width, RS232 serial
Small, lightweight module
Designed for easy integration into your project or product
Real-time automatic calibration (voltage, humidity, ambient noise)
Firmware filtering for better noise tolerance and clutter rejection
Weather Resistant (IP67)
200,000+ Hours Mean Time Between Failure
Matches standard electrical pipe fittings for easy mounting
The mid-range, narrow detection zone
Additional stability filter rejects occasional anomalous readings
Detects the largest signal return in the field of view
Uses the complete dynamic range of the sensor, if no large targets are present the sensor will select the next smallest target in view
Can be used to range large objects behind small obstructions
