OneWire requires a single 4.7K pullup resistor, connected between the pin and your power supply. When using very long wires, or with counterfeit DS18B20 chips and 3.3V power, a resistor in the 1K to 2.7K range may be required. Then just connect each 1-wire device to the pin and ground...
Temperature (DS18B20) pH (Atlas EZO pH) Flow (hall effect flow sensors) Leakage (generic moisture sensors) Stock solution level (level switch sensors) Getting Notifications: all of the sensors which output data can be monitored against min/max thresholds. A notification is sent to your mobile ...
This all-in-one microcontroller allows for easy connectivity to a LoRaWAN network while maintaining the Arduino simplicity you know and love for prototyping. First, let’s tackle the sensor wiring. Here is a list of the sensors you will need: DS18B20 Temperature Sensor (Waterproof) Soil ...
