2023 IOTE IoT Exhibition Review | Angle Sensors

This exhibition is an IOTE international IoT exhibition that brings together over 600 participating companies from around the world, as well as over 130000 professional integrators and end users from industries, healthcare, infrastructure, smart cities, and smart retail.

<Booth consultation>

At this exhibition, Jingweite brought in smart home and IoT supporting solutions, including inertial navigation series modules, 2.4G RF communication modules, angle sensors, ultrasonic liquid level sensing modules, and pet smart water dispenser control boards.

These products are arranged in an orderly manner on our booth, attracting attendees who come and go. After a simple understanding, everyone will be interested in learning more!

In just three days, the participants who came to consult were in high demand. Through this exhibition, customers in the industry have gained an updated understanding of the unique features of Jingwei. Through this exhibition, we have also made many friends from both inside and outside the industry. We believe that with further understanding, we will have more cooperation.

<Exhibition Review - Angle Sensor>

At this exhibition, many attendees were very interested in angle sensors. Here, the editor will review for everyone. This is a new generation of angle sensors that use tunnel reluctance (TMR) sensors and CMOS signal processing circuits to integrate non-contact, high-speed

High precision digital magnetic rotary encoder chip.

The product contains tunnel magnetoresistance (TMR) sensors and signal processing circuits inside. Through the TMR sensor, the rotation of a pair of polar magnets above the chip is sensed, and the rotating magnetic field signal is collected and transmitted to the digital processing unit,

Calculate the rotation angle and use SPI communication protocol to output a 14 bit absolute position signal. At the same time, output a programmable incremental position signal of 1-4096 pulses for A/B phase, as well as a programmable zero position (Z-phase) signal. Additionally,

It can also output UVW commutation and PWM signals, with a maximum speed of 25000 RPM.

Internally integrated with EEPROM, configuration parameters can be rewritten multiple times. In addition, we provide a convenient self calibration mode for the client, which can compensate for the nonlinear errors caused by structural installation through self calibration.
