Deep soil sensors
Posted: 10 Feb 2018, 14:35
Have done an experiment with several soil sensors, and concluded that with SHT11 with a certain quality you can measure temperature and humidity to a certain depth underground: see https://www.vannwnhzn.nl/esp8266a5_humtemp01.html
Empirically proven that prolongued immersion of an SHT11-sensor is not fatal:
measurement of temperature continues, but after some time the value of measurement for humidity from >100% drops to nil.
The experiment under my house made me start thinking about measurement in my garden at depts of -10cm, -20cm, -50cm and -100cm.
Is it technically/functionally possible to interface 3 or 4 SHT11-sensors at 1 ESP/WEMOS? Howto?
