!!!OLD VERSION FOR IoTv3!!!<\/h2>\n\n\n\n

1. Connect several sensors to the pin in parallel (pin 2 is immediately tightened and the resistor is not needed, but do not turn on the wi-fi indicator in the web interface -the same pin is used)<\/p>\n\n\n\n

2. Create the required number of sensors in the web interface<\/p>\n\n\n\n

3. If there are three sensors, for example, then in the line of the first sensor in the web interface, you need to write index[0], the second index[1], the third index[2], etc.<\/p>\n\n\n\n

In the latest firmware versions, you can connect multiple ds18b20s<\/p>\n\n\n\n

1. Create the required number of sensors in the web interface<\/p>\n\n\n\n

2. In the same place, change the pin numbers to which the sensors are connected<\/p>\n\n\n\n
