A case cover for multiple Soil Sensor Hygrometer Module V1.2 connected with an ESP32-C3 Mini or ESP32-S2 Mini. I think this cover is optimally sized, once your printer is calibrated the cover fits perfectly, but I recommend to use some hot glue to ensure to be water resistant. The cover protects the electronics from soil and water. In my case I extend the cable sizes (one plant pot is 2 meters distant from ESP) using a wire from a network cable. My soil sensors are configured in Home assistant, its possible to configure with ESP32 and ESP8266, but in my experience ESP32 is much more stable for this and use less energy (if you use sleep mode). Here a sample of this configuration: sensor: - platform: adc pin: GPIO2 name: "Soil Moisture 1" unit_of_measurement: "%" device_class: MOISTURE update_interval: 5s attenuation: 12db filters: - calibrate_linear: - 1.45 -> 100.00 - 2.821 -> 0.00 - lambda: | if (x < 0) return 0; else if (x > 100) return 100; else return (x); accuracy_
