Blueberry 868 MHz Transmitter/ Receiver With SHT21 Temperature And...
Blueberry Home Solutions Smart Hub for Raspberry Pi - Blueberry TXRXTempHum, The Blueberry wireless temperature and humidity sensor features an on-board ATMEGA329P microcontroller(MCU) giving it all the programmability and convenience of an Arduino. There is a dedicated showerproof ABS case (75-0604) for this board together with a PP3 battery. By using the sleep functions of the RFM21B sensor and ATMEGA328P, a PP3 battery will allow the board to transmit for up to a year. The transmission range is up to 300m and the data rate is up to 115k bits per second using a Hope RFM21B tranceiver module. The transmission protocol supports 250 different network groups with 30 nodes per network; by using the MCU this can be greatly extended. The wireless frequency is set to 868MHz for use in Europe,
by default. Settings are available for other regions around the world.The ATMEGA328P is the same processor used on the Arduino UNO and this board can be programmed in the same way using either the Arduino IDE or your own preferred tool chain. Briefly, the MCU has 32Kbytes of flash memory, 1Kbyte of EEPROM, 2Kbyte RAM, 23-GPIO lines, 3 timers, 6 x 10-bit A/D channels. This programmability allows you to add additional sensors or to control other devices, greatly extending the usefulness of this clever little board.This module is compatible with the Blueberry 4-character 14-segment alphanumeric display (75-0602), simply plug the two together, apply power (from a PP3 battery for example) and the display will show the temperature and humidity being updated at regular intervals.
Communicate wirelessly with the Blueberry Internet of Things Controller (75-0600) which also has an 868MHz transceiver and because each sensor has a unique ID, multiple sensors can be linked to the same controller. Blueberry 868 MHz Transmitter/ Receiver with SHT21 Temperature and Humidity Sens
