PI RF METEO STATION
The main idea is described in photo below:
Raspberry PI is connected via 26 PIN 2,54' IDC HEADER cable to PISENSOR Board which has wired and wireless connection to sensors. Sensors is connected via I2C bus using only 4 pin : VCC,GND,SCL,SDA.
Pisensor is simple board for sensors using i2c bus and wireless transceiver NRF24L01+.
Attached below you see sensor overview with descriptions:
pisensor.pdf
and below you see pcb schematic:
13 row 26ping header is the same as in RPI. On board we have also digital termometer TCN75V0A.
At right side we have socket NRF to attach NRF24L01+ radio module. Also we have 3xVcc and 3xGnd pin at left side and 6 pins (G17,G22,G24,G18,G21,G23) - special function RPi GPIO pins.
The main idea is to connect special sensor to this board
can you give more code from i2c communication betwen attiny an raspberry.
