IOT123 - I2C DHT11 Brick

The IOT123 BRICKS are DIY modular units that can be mashed up with other IOT123 BRICKS, to add functionality to a node or wearable. They are based on the inch square, double-sided protoboards with interconnected through holes.
A number of these BRICKS are expected to be on multiple nodes (Master MCUs - ESP8266 or ATTINY84) on a site. The MCU needs no prior knowledge of the sensors purpose or software needs. It scans for I2C nodes then requests a property dump (sensor data) from each slave. These BRICKs supply 5.0V, 3.3V and another line for an upcoming sensor voltage standard (1.2V/1.5V/1.8V/2.5V).
This I2C DHT11 BRICK dumps 5 properties: Humidity (%), Temperature (C), Temperature (F), Temperature (K), Dew Point (C).
The Keyes type sensor bricks will be abstracted first as they come with vitamins (extra components needed) included and are relatively cheep (I bought 37 for 10AUD). Other boards/circuits will be introduced to the I2C BRICKS.
The through-holes adjacent to the ATTINY85 have been left unused, to enable a pogo pin programmer while the DIP8 is soldered to the PCB.
A further abstraction, packaging the BRICKS in small cylinders that plug into a D1M WIFI BLOCK hub, pumping the values to a MQTT server, is being developed.”
