The RN2903, a low-cost, low-power transceiver with LoRa technology, is used for long-range transmission and reception of data. As a member of the growing family of low-power transceivers, the RN2903 is one of the most cost-effective LoRa transceivers on the market. It is integrated into many products to communicate wirelessly over long distances.
The RN2903 LF is a low-frequency CN2903 variant designed specifically for the control and tracking of small assets in secure installations. It provides a low-power solution for the monitoring of assets in an area where RF communication is not feasible. The device uses the long range capabilities of LoRa technology to track assets over a long distance, with minimal power consumption. The RN2903 LF is also pre-programmed to support key security protocols.
The RN2903 LF is ideal for CT (Current Transformer) applications and is capable of measuring current and providing current values over LoRaWAN networks. The device is also compatible with other transceiver technologies, making it ideal for a variety of applications. It offers the capability to measure both current and power, and is capable of transmitting the relevant data to a receiver, such as a base station or gateway. The device has two digital input/outputs that can be used to control external devices or read data.
The RN2903 LF also offers a number of features for improved reliability, such as an integrated Temperature Sensor, a Vibrate Sensor, a battery level monitor and a robust RF link. The device is also designed to minimize power consumption, with a range of features, such as a Sleep Mode, that allow it to extend its operating life. The RN2903 LF has a Power Save Mode (PSM) that can be used to reduce current consumption when the device is inactive, providing significant energy savings.
The RN2903 LF is designed to operate in the license-free, ISM (Industrial, Scientific and Medical) frequency band. This provides the device with a global coverage range, making it ideal for a wide range of applications. The device supports both uplink and downlink communication, and is capable of transmitting data over long distances. The RN2903 LF is a low-cost and low-power transceiver, making it ideal for asset tracking and monitoring applications.
The working principle of the RN2903 LF is based on a current transformer. A current transformer is a device used to measure current in an electrical circuit. It works by creating a magnetic field around an electrically isolated conductor and then measuring the current in the circuit by reading the strength of the magnetic field. The RN2903 LF is designed to measure the current in the circuit and then transmit the data to a gateway or base station using LoRa technology.
