SK200 : 1W LoRa Industrial Anti Interference Wireless Switch Module
- SK200 is an industrial grade remote single-channel wireless switch module. It consists of the transmitter module SK200-TX-1W and the receiver SK200-RX with a transmission power of 1W. The design adopts LoRa spread spectrum modulation frequency hopping technology, which has high receiving sensitivity and superior anti-interference performance. Its communication distance and receiving sensitivity far exceed FSK and GFSK modulation. The module provides a single signal input and a single control output interface. It has the characteristics of simple interface and reliable operation. Users can configure the internal parameters of the modified module in combination with our PC interface. Many pairs of simultaneous communication will not interfere with each other, and the use is flexible and convenient. The system can easily replace the original wired environment with wireless control, which greatly reduces the cost of manual wiring and is widely used in industry.
- SK200 strictly uses lead-free process for production and testing, and meets RoHS and Reach standards.
