- How to do ESD Protection for RF Module Products in Hardware Design？ESD protection design mainly refer to shell design, hardware design, PCB layout, component selection, software debugging, etc. In hardware design, an important method is to add ESD protection devices at key circuit nodes. For a wireless module with external antenna, the antenna interfaces need to be addedFAQ June 16, 2021
- Application of LoRa Module in Smart Meter ReadingNowadays, the application of remote wireless transmission is increasing year by year, such as small amount of data between devices like water meters, smoke detectors, and the use of long-distance transmission. Let's take Smart Water Meter reading system as an example, to explain how LoRa module works in the AMR.FAQ December 30, 2020
- How Window/Door Sensor Works?Door Sensor is composed of a wireless transmitter module and a magnetic block. There is a "reed switch" inside the wireless transmitter module. When the distance between the magnet and the reed switch is within 1.5cm, the reed switch is disconnected. Once the distance exceeds 1.5cm, it will alarmFAQ October 15, 2020
- What are PIR Sensors and How they Work?PIR Detector is a sensor that detects the movement of the heat source object. With the help of an optical system, it can detect the change of thermal radiation in a certain defense space. The PIR Detector converts the received change of IR heat radiation energy between the active human body and the background object into a corresponding electrical signal, and then alarms.FAQ May 14, 2021
- IoT Market Growth Will Slow Down Due to the COVID-19 PandemicThe total number of wireless IoT connections will increase from 1.5 billion at the end of 2019 to 5.8 billion in 2029. But the growth rates for the number of connections and connectivity revenue will be somehow lower than previous forecast. This is partly due to the negative impact of the COVID-19 pandemic...
- How to choose the corresponding 433m wireless moduleWhen it comes to the Internet of Things, we should all be familiar with the development of the Internet of Things today, and it is also gradually entering the field of the market. Slowly with the artificial intelligence, production machinery, no matter whether it is in our lives ...FAQ June 06, 2020
- What is Switching Value RF Module?Switching value signals is a digital signal. Compared with analog signal, it has strong anti-interference ability. The change of the switching value signal is not continuous, so it is so called pulse signal. If an RF module uses switching value signals to communicate, we call it Switching Value RF module.FAQ December 22, 2020
- How to Choose a Suitable 2.4Ghz Wireless Module?The 2.4G wireless module works in the worldwide application-free ISM band. This band has relatively little interference, high frequency but weak penetration ability.
