See http://iot-playground.com/ for details

IMPORTANT: use correct firmware version together with EasyIoTESP8266 Arduino library. Use ESP8266 firmware version 0.952. You can download fw on this link: http://iot-playground.com/2-uncategorised/35-esp8266-firmware-flashing If you are usning SW serial, set baudrate to 9600 (default is 115200) with AT+CIOBAUD=9600

NRF24L01+ Arduino low power sensors

See http://iot-playground.com/ for details

nRF24L01 is a single chip radio transceiver for the world wide 2.4 - 2.5 GHz ISM band. The transceiver consists of a fully integrated frequency synthesizer, a power amplifier, a crystal oscillator, a demodulator, modulator and Enhanced ShockBurst™ protocol engine. Output power, frequency channels, and protocol setup are easily programmable through a SPI interface. Current consumption is very low, only 9.0mA at an output power of -6dBm and 12.3mA in RX mode. Built-in Power Down and Standby modes makes power saving easily realizable.
