Universal board for Arduino Nano and UNO and Nano shield with NRF24L01 transmitter, 16x02 LCD I2C SPI (PCF8574) display, two KY-040 Rotary Encoder, GY-521 ITG/MPU (MPU6050), Adafruit 9DOF (LSM303DLHC+L3GD20), MH-FMD BUZZER, DHT11 Humidity & Temperature Sensor, BME280 Pressure Humidity Temperature Sensor Module, MQ-8 and MQ-9 GAS SENSOR, With additional areas for dip and soic.
Homely WSN Basic Board V2 is an IoT board to collect environmental data (temperature, humidity, and pressure) and to push them to a centralized server through Wi-Fi. This is the enriched successor of the Basic Board V1, that improves different aspects:
- energy efficiency (20uA during deep-sleep)
- onboard recharge for single-cell Lipo battery
- measurement of battery level based on voltage*
Powered by 2 AA Batteries Size 20 x 45 (mm) Almost SMD 0805 Atmel328p TQFP32 NRF24I01 smd ATSHA204A chip FLASH for OTA FTDI, ISP SHT21 Sensor
The Sensor works directly on two AA Batteries or Ni-MH.

Temperature, humidity and luminance sensor based on ESP12-E (ESP8266).
- The temperature and humidity sensor is DHT22, but you can setup any other.
- The pir sensor could be any with abinary digital output.
- The luminance sensor is based on ADC
USB port is only for power (you can also power it by the header male pins).
For programming you have to use the UART pins.

**Description**:The **HTU21D** is a low-cost, easy to use, highly accurate, digital humidity and temperature sensor. This sensor is ideal for environmental sensing and data logging and perfect for a weather stations or humidor control systems. All you need is two lines for I2C communication and you’ll have relative humidity readings and very accurate temperature readings as a bonus!
