FAQ
Frequently Asked Questions about DF703 Smart Waste Bin Sensor
What does the DF703 waste bin sensor detect?
DF703 detects four key waste bin statuses: fill level (full/empty), flame risk (fire detection), tilt/fall (inclined), and bin position. It uses 40 kHz ultrasonic sensing for fill-level measurement with up to 4 m detection range and 15 cm blind area.
Which wireless versions are available for DF703?
DF703 is available with NB-IoT, LoRaWAN, 4G LTE, and multi-mode NB-IoT + Cat-M wireless versions. The 4G version supports global LTE frequency bands. Data upload uses TCP or customized protocols, with SDK support in Python and JavaScript.
How long can the DF703 battery last?
DF703 uses one ER26500 non-rechargeable lithium thionyl chloride battery with 8500 mAh at 3.6 V. Under reference conditions (upload 4 times per day, cycle detection every 10 minutes, without GPS), battery life can exceed 3 years. Actual life depends on ambient temperature, upload frequency, and wireless signal strength.
What optional features does DF703 support?
DF703 supports two optional features: Bluetooth configuration for convenient local parameter setup, firmware upgrade, and maintenance without TTL wiring; and GPS/BEIDOU positioning for locating movable bins or containers that are frequently repositioned.
What certifications does DF703 have?
DF703 has CE, FCC, and RoHS certifications. The enclosure is rated IP68 for outdoor waterproof protection and IK10 for impact resistance, making it suitable for long-term outdoor waste bin deployment.
How is DF703 installed on waste bins?
DF703 is typically installed on the top cover of a waste bin using screws and the included metal bracket. The sensor should be mounted as vertically as possible for reliable ultrasonic measurement. It is suitable for both covered and uncovered trash cans.
