When the epidemic broke out, people didn't grab masks but rushed to ask for meters


2020 is destined to be an extraordinary year. The emergence of novel coronavirus pneumonia has given people unprecedented cohesion, and there are countless moving and gratitude behind the situation. With the efforts of many people, we are about to gradually resume life and production, but the world is also undergoing tremendous changes.


With the outbreak of the global epidemic, not only masks and protective equipment are in short supply, but temperature measuring guns have also become tight products. In recent days, YTL, which is mainly based on foreign trade, has also received the demand for infrared thermometers from foreign customers.


Foreign Client:

YTL, we urgently need infrared thermometers. Your research and development capabilities are so powerful, please help us design an infrared thermometer.


Hello, I'm really sorry, our company only makes electric measurement products, not infrared thermometers.

Foreign Client:

With so many products and strong R & D capabilities, can you make adjustments to the existing plans?


Well, we also hope to make some contributions to fight the epidemic. Technicians already have ideas, on the basis of the electric meter of our charging pile, replace the measuring head with a thermopile sensor and simplify the circuit to be a temperature measuring gun.


In view of the strong demand from foreign customers, the final sentiment still overcomes the rationality. We designed a solution for the temperature measuring gun for our customers. Here we show the solution.(Reiterate: YTL does not make temperature measuring guns. After the design scheme is made by customers, we only make electricity measurement and measurement products.)




Introduction of infrared thermometer program: YTLA124 is packaged in SOP8, which is a high-precision and low-power 24-bit analog-to-digital conversion chip, with built-in 128 times instrument operational amplifier. The ADC data output rate in normal mode is: 10Hz ~ 1.28KHz, the default is 10Hz. The MCU can communicate with the A124 via the 2-wire SPl interface. The maximum rate is 1.1MHz. 1 way 24-bit differential input without failure codes, ENOB is 20 bits when PGA = 128.

Remind: After the epidemic, the price of the temperature measuring gun will drop greatly, and it will not work without a good cost performance!


Zhejiang Yongtailong Electronics Co., Ltd. is a national high-tech enterprise integrating R & D, production, sales and service of professional electronic energy meters and other power measurement, control and service products. It has always been committed to research and development in the field of power measurement and energy saving, and make cost-effective products and services to create value for customers. Combining with the current Internet of Things technology, YTL Smart Energy Management System came into being. Small meters provide accurate data and diverse services to achieve prepayment, energy saving, safety and predictability, create a green, energy-saving, safe and secure electricity environment for customers.
