custom PCB

TODO: v1 and v2 - process/price. errors/bugs. v1.0/1.1 v 1.0 v 1.1 Changes I want to make: smaller. fix missing connection. fewer I²C connections (used + 2). no 1-wire. text visible. more JCT connectors instead of pins. 38 pin esp32?

esp32

TODO: many GPIOas, integrated wifi (and bluetooth)

interfaces

TODO: (I²C, 1-Wire, Analogue input, Digital input)

deep sleep

TODO: striggle with mulitple buttons

temperature

TODO: hide from sun, calculate average, soil temperature

soil moisture sensors

TODO: tried both capacitive and resistive, struggling with good calibration

batteries, solar panel

TODO: which batteries, how many, which solar panel

windows

TODO: how to measure the "openess"?

wifi, antenna

TODO: wifi 50 meter outdoor through walls. Hacked antenna on a 30-pin

light sensor

TODO: tried 3 different locations - ended up with hald-dome diffuser in roof top. Typically will not measure anything below 0.5lux or higgher than ca 50000lux.

Ideas and Future

simple

TODO: add outside temperature (hm - how/where).

complex

ideas on actually controlling:

• watering
• nutrition
• light
