Editorial narrative

Product Description RAK1903 is a WisBlock Sensor based on Texas Instruments OPT3001 chip which extends the WisBlock system with ambient light sensing capabilities. A ready to use SW library and tutorial makes it easy to build up an ambient light data acquisition system. RAK1903's range from 0.01 lux to 83865 lux makes it suitable for a greenhouse control system, light detection system, or alarm systems. RAK1903 combined with the RAK4631 WisBlock Core is ready to go system to collect ambient light data. The acquired data can be send using LoRaWan® communication, LoRa® point to point connections and BLE. RAK1903 is ideal for battery-powered applications because of its low power consumption. In addition, the WisBlock system allows to power down the module complete to reduce the power consumption of the system even more. RAK1903 ambient light sensor can be combined with other WisBlock sensors like a temperature and humidity sensor and a barometric pressure sensor module to create a greenhouse control system. Key Features Using the TI OPT3001DNPR light sensor Low power consumption Small form factor Measurement range from 0.01 lux to 83865 lux Optical filtering to match the human eye Low power consumption of 1.8uA Package Inclusions 1pc RAK1903 Documentation RAK1903 Quick Start Guide Datasheet WisBlock Quick Start Guide WisBlock Source Code Repository (opens new window) RAK1903 3D Model (opens new window) 24-Pin Male Connector 3D File (opens new window) WisBlock Sensor Tutorial Examples For All WisBlock Core Modules: Sample Code: RAK1903 (opens new window) For WisBlock Core RAK4630: Sample Code: Weather Monitoring (opens new window) LoRaWAN Weather Monitoring Kit with WisBlock RAK1903 LoRaWAN Weather Monitoring Kit Tutorials WisBlock Starter Kit and RAK Edge Gateway Complete LoRaWAN Guide Installation of Board Support Package in Arduino IDE The Icing on the Cake: A Template to Innovate Custom IoT Applications with RAKwireless and Datacake Work in a Well-lighted Environmen
