The best waste bin fill-level sensor depends on how its readings will connect to your monitoring system. The DYP-A13 is a strong option when you need a 25–200 cm ultrasonic range and a particular output, such as UART, PWM, or RS-485. A separate A13 listing mentions low consumption and NB-IoT support, while a float sensor may suit a waste tank rather than an open bin. Check interface, measurement range, and installation requirements before choosing.

DYP-A13 UART Automatic Sensor
This DYP-A13 version is best for a waste-bin monitoring setup that needs automatic UART output. The listed measurement range is 25 cm to 200 cm, with millimeter resolution. The sensor also lists PWM, UART-controlled, switching, and RS-485 output types as available options across the A13 module family.
Its small beam angle and high sensitivity are described as helping detect objects with weak sound-wave reflections or small reflective areas. Firmware filtering is listed for noise tolerance and clutter rejection. Choose this version if automatic UART output suits your controller. Its listed range may not suit bins or installation positions outside 25–200 cm; confirm the measurement geometry before buying.
DYP-A13 PWM Output Sensor
This version is best for buyers whose control equipment reads a PWM pulse-width signal. The listing gives the A13 a 25–200 cm range and millimeter resolution, and describes a narrow beam and high sensitivity. Firmware filtering is intended to improve noise tolerance and reject clutter.
It was selected as a distinct output choice, not as a different measurement technology. Check that your system accepts the specified PWM output before choosing it. The listing also mentions UART and RS-485 types for the module family, but this product name identifies the PWM version; do not assume the other outputs are active on this unit.
DYP-A13 UART Controlled Sensor
The UART-controlled version is best for buyers who need a command-based UART configuration rather than automatic reporting. The listing specifies a 25–200 cm measurement range, millimeter resolution, high sensitivity, and firmware filtering. Its small beam angle is described as supporting detection of targets with limited reflective area.
Choose this sensor when the system design calls for controlled UART output and the target distance falls within the stated range. It is not the same output configuration as the automatic UART version, so verify the required communication behavior before ordering. Product information does not specify wiring details or setup instructions.
DYP-A13 RS-485 Sensor
This version is best for a bin-monitoring installation designed around RS-485. The A13 listing describes millimeter resolution, a 25–200 cm range, a small beam angle, and firmware filtering for noise and clutter. These are useful selection details when comparing the sensor’s measurement capability with a bin’s dimensions and internal layout.
Choose this model if RS-485 is the required interface. Avoid selecting it solely because the A13 family lists several output types: this product is identified as the RS-485 version. The supplied information does not give protocol settings, wiring, or environmental protection details, so confirm those requirements with the seller or documentation.
A13 Low-Consumption NB-IoT Sensor
This A13 listing is best for buyers researching a low-consumption sensor with NB-IoT support. The product title also describes a small beam angle and bin fill-level use. Those details make it relevant to remote smart-bin projects, but the supplied feature information is limited to the title and a proximity-sensor category.
Choose it only after confirming the actual communication hardware, power requirements, range, and output details. Unlike the DYP-A13 listings above, this product’s provided information does not state a measurement range or millimeter resolution. That lack of specifications is its main limitation for planning an installation.
Buying Guide: How To Choose A Waste Bin Fill-Level Sensor
Which output should the sensor use?
Match the sensor output to the controller or data-acquisition system. UART automatic and UART controlled are different configurations; PWM provides a pulse-width output, while RS-485 is a separate interface choice. Do not assume one product includes every output mentioned for the broader A13 module family.
Will the range fit the bin?
For the DYP-A13 models, the listed measurement range is 25–200 cm. Compare this with the sensor-to-waste distance at both empty and full conditions. Keep the sensor positioned so the expected surface is within the stated range, and consider whether bin walls or irregular waste could interfere with the measurement.
What do beam angle and filtering mean?
A small beam angle can help focus measurement on a more limited area. The A13 listing also describes high sensitivity and firmware filtering for noise and clutter rejection. These features do not replace checking the installation layout or confirming performance for the materials and conditions in a specific bin.
Is NB-IoT support essential?
Choose an NB-IoT-oriented product only if its communication and power details fit the intended system. The supplied details for the separate A13 NB-IoT listing do not specify range or electrical requirements, so request complete documentation before designing around it.
Frequently Asked Questions
What does a waste bin fill-level sensor measure?
An ultrasonic fill-level sensor measures the distance to a target surface. A monitoring system can use that distance to estimate how full the bin is, depending on its setup.
Which DYP-A13 version is best for UART?
Choose the UART Automatic version for automatic UART output or the UART Controlled version when the setup requires controlled UART output.
Do these DYP-A13 listings state a measurement range?
Yes. The listed range is 25–200 cm, with millimeter resolution.
Can I assume the NB-IoT listing has the same specifications?
No. Its supplied details mention low consumption, a small beam angle, and NB-IoT in the title, but do not state the DYP-A13 range or resolution.
