Wireless Ultrasonic Level Sensor for Small trash bin WS433-ULA

Introduction

WS433-ULA is a Sub-GHz wireless ultrasonic level sensor to measure solid surface level in the trash bin for waste management systems ... This level sensor uses ultrasonic technology to measure the solid surface of waste, the principle is to measure the time of flight of the ultrasound pulse in the air environment. The ultrasound pulse will be ejected from the ultrasonic transducer, go thru the air and reach the solid surface of the waste, then reflected back to the ultrasonic transducer, the measuring circuit will measure the flight time of the pulse then calculate the distance from the transducer to the surface. The ultra-low power design and smart firmware allow the sensor to last for up to 10 years with just 2 x AA batteries (depending on configuration). The sensor will connect wirelessly to a Wireless Coordinator WS433-CL then export the data to RS485 / Modbus RTU and from there easily connect to any monitoring and control system. LOS distance from the sensor to the receiver is 1000m and can be extended by Extender.
