It measures the distance to the nearest target from 20 cm to 350 cm with centimetre resolution at a fast 10 Hz read rate, outputting data via analogue voltage, pulse-width, or RS232 serial.\n\nHoused in a rugged PVC enclosure rated IP67, the sensor fits standard ¾-inch electrical PVC pipe fittings for easy mounting inside bins and containers. Factory-calibrated narrow beam patterns and advanced noise rejection provide reliable readings in harsh outdoor environments.\n\nKey Features\n\n\nDesigned for Waste Monitoring – Optimised for measuring fill levels in bins and containers\n\n20–350 cm Range – Short to mid-distance detection with 1 cm resolution\n\n10 Hz Read Rate – Fast, responsive measurements\n\nIP67 Weather Resistant – Rugged PVC housing, sealed against water and dust\n\nThree Output Modes – Analogue voltage, pulse-width, and RS232 serial\n\nReal-Time Auto-Calibration – Compensates for voltage, humidity, and ambient noise\n\nLow Power – 3.4 mA average current draw\n\n200,000+ Hours MTBF – Designed for long-term, maintenance-free operation\n\n\nSpecifications\n\n\nSensor Frequency – 42 kHz ultrasonic\n\nDetection Range – 20–350 cm\n\nResolution – 1 cm\n\nRead Rate – 10 Hz\n\nOperating Voltage – 3.0–5.5 V\n\nAverage Current – 3.4 mA\n\nOperating Temperature – −40 °C to +65 °C\n\nIngress Protection – IP67\n\nCompliance – RoHS\n\n\nIdeal For\n\nSmart waste bin fill-level monitoring\nIoT waste management and collection optimisation\nContainer and tank level sensing\nOutdoor environmental monitoring\n\n\nResources\n\nXL-TrashSonar-WR Datasheet (PDF)\n","vendor":"DFRobot","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":4932,"title":"Default Title","sku":"DF-SEN0283","price":243.76,"on_sale":false,"in_stock":true,"available_quantity":8,"option1":"Default Title"}]}
