I have a broad question as I’m attempting to create a temperature monitor system for up to 4 aquariums using the DS18b20 Waterproof Temperature Probes. I’m wondering if I will be able to utilize something like an ESP32 to have all 4 probes connect to a single board OR if I will need individual boards for each probe. It appears as though they will require 5V, GND, and a data pin. Based on my high-level research it looks as though the ESP32 will have more pins available than say an ESP8266. Any idea if there is a single SparkFun board that could handle 4 individual temp probes to fit this task? In addition, I’m looking for WiFi or Ethernet as I want monitoring back to a platform such as Home Assistant via NodeRed or MQTT to receive notifications when the temps go outside of predefined parameters.
Thanks in advance!
