product details

Introduction:

The LoRa smart water meter uses "Internet of Things networking counting technology" to achieve a balance between reliable communication and low power consumption, using a licensed 470MHz dedicated meter reading frequency. The LoRa module adopts current ultra-low power MCU and RF chips, and modifies the characteristics of low-power MCU according to the 802.15.4 specification, greatly improving its transmission efficiency on the basis of low energy consumption. The open transmission distance exceeds 1.2km, with a theoretical distance of 5km. This meter has the characteristics of high reliability, high accuracy, and low power consumption.
