Application Notes
Recommended and not-recommended deployment scenarios
Recommended Applications
- Indoor waste bins
- Indoor open-top bins
- Outdoor covered waste bins
- Outdoor bins with top-cover installation
- Smart waste management with collection verification
- Commercial complex waste management
- Campus and park waste bin monitoring
- Street-side covered bin monitoring
Not Recommended

FAQ
Frequently Asked Questions about DF704
What makes DF704 different from DF703?
DF704 uses laser ToF multi-point measurement (4x4 matrix, 16 points) instead of single-point ultrasonic. It adds 125kHz LF RFID vehicle identification and edge AI processing for surface profile estimation, collection verification, and smarter event recognition.
How does the multi-point detection work?
DF704 uses a laser ToF 4x4 measurement matrix with 16 detection points. It captures height distribution across the waste surface, restores the surface profile, and calculates fill-level more accurately than single-point sensing.
How does RFID vehicle identification work?
A 125kHz LF exciter on the collection vehicle wakes DF704 from 1-2 m away. DF704 identifies the vehicle, triggers measurement, and uploads collection event data. Collection completion is determined by waste height change and edge AI processing.
Can DF704 be used in outdoor bins?
DF704 is recommended for indoor waste bins and outdoor covered bins. Outdoor open-top bins are NOT recommended because direct sunlight may reduce laser ToF detection distance and measurement reliability.
What wireless versions are available?
LoRaWAN (multi-band), 4G (Asia/Europe/North America), Cat-M+NB-IoT, and NB-IoT. Final configuration depends on the selected module and target region.
How long does the battery last?
Approximately 2 years with one ER26500 battery (8500 mAh). Battery life depends on ambient temperature, signal strength, upload frequency, detection frequency, LF wake-up frequency, and GPS usage.
Is the LF exciter included with DF704?
No. The 125kHz LF exciter is sold separately and is not included in the standard package. The standard package includes the DF704 sensor, one ER26500 battery, two M4x30 screws, one metal bracket, and one serial configuration tool per order.
Is DF704 a standard product?
DF704 is available for pilot projects and small-batch pre-order programs. It is suitable for customers validating next-generation smart waste features before rollout. Quotation-based pricing.
