Relay:
**One Relay:**
rated to 10 or 16 amps (Input voltage: 90~ 250V AC)
Jack socket 2.5mm:
**One Jack socket 2.5mm:**
The jack socket make the most interesting difference to a Sonoff Basic. The jack socket connects clean to GPIO14.
Sonoff sensors with 2.5mm jack:
Sonoff sells 3 sensors with 2.5mm jack, which are offered to use with the Sonoff Th. Sonoff TH Sensor Si7021 / Sonoff TH Sensor-AM2301 / Sonoff Temp Sensor-DS18B20. Lengs of the wire are approximately 47cm. The DS18b20 come with a wire length of approximately 1m. Sonoff Th and all 3 Sonoff sensors are supported in Tasmota. **It's important to clarify: A Si7021 sensor is out of the box a i2C device. The "Sonoff Si7021 sensor" is BASED on an Si7021. To make it plug&play with a Sonoff Th, an 8-bit MCU is added on the board. This changes the i2C communication of an Si7021 sensor over to a 1-wire device ! **
