We have as parts:

• Adafruit HUZZAH with ESP8266 as MC
• HX711 breakout as load cell amplifier and ADC
• two resistors (2x 4.7 kΩ) for the sensors (DHTxx and DS18B20)
• two resistors (1 MΩ, 220 kΩ) as voltage divider to measure the battery drain * [an additional capacitor in parallel to the lower resistor is recommended but not prepared on the PCB yet]
• screw terminals
• for the PCB we need also a CN3065 breakout, this is the solar charging IC (not provided in the bread board version)
• custom PCB
