The product is based on a liquid sealed cold water meter, with a stainless steel cover and a counter display of black background and white letters. Attach a camera wireless remote transmission device to the water surface. During meter reading, the camera captures the numbers and the microcontroller parses the image into data. Wireless communication uploads data to the concentrator. Automatically screenshot and upload digital images.
The product is wireless remote transmission. Use GSFK or LORA communication in the radio frequency range of 470MHz to 510MHz.
