ESP8266 + AGIRS + DHT + NON_MOD 433 TX
Building on the Agirs nano adding a DHT11 and a NON_MOD transmitter.
The code for this board (when finished) will include an oregon scientific temperature transmitter, and the ability to transmit and receive IR signals with the added bonus of transmitting other OOK signals via the same protocol.
All of this accessible over ESP8266 wifi.
The design puts the radios facing opposite directions on the sides and the IR/visible LEDs and receivers facing the same direction.
Designed as a single layer PCB for ease of home etching.
Pre-heat your boards before toner transfer to shrink them in so they don't change size when you heat for transfer.
