Requires an Ethernet Tag Manager. 

Outdoor Probe Basic supports connection of either a DS18B20 waterproof  temperature probe or a I2C-based temperature+humidity probe such as SEN0385 (supported since July 2021), SEN0227 or other compatible SHT2x or SHT3x based probes such as this.  DS18B20 temperature probes (1m) can be either purchased together with this product, or from Amazon and other vendors such as Adafruit (no external resistor is necessary). DS18B20 with cable length up to 10m have been tested to work reliably. 

Perfect for monitoring and logging temperature of swimming pool, sauna, freezer (where humidity may exceed 95%) fish tank etc.  

Features (see also feature matrix)

• IP68 rated (completely water and dust proof)
• Temperature logging and notification with 0.0625°C resolution temperature sensor and +/-0.5°C error (spec for DS18B20 probe)
• With 16K points of local memory, temperature recording keeps running during a trip, power or Internet outage of up to 10 weeks (at 5-minute logging interval.) Put inside shipping container, vehicles, etc to log temperature throughout the trip. Automatically uploads the temperature and humidity data to cloud when back in range, and builds seamless graphs.
• Enhanced temperature monitoring while in range (Learn more)
• Logging interval programmable from 30 seconds to 4 hours. The "transmit multiple data points at a time" mode improves battery life and allows shorter logging interval. 
• Out-of-range/back-in-range notification
• Unlimited storage of logged temperature, humidity and motion event data on cloud (can be deleted any time)
• Accepts one DS18B20 or SHT20 based external probes with cable diameter between 4mm and 8mm. 
• Works with Amazon Alexa and Google Home
• 3 year limited warranty

Includes a 3.6V 1200mAh 1/2 AA battery (where to buy replacement) for reliable operation over a wide temperature range (-55°C to 85°C, vs. -30°C to 60°C of a regular CR2032 battery in other tags), and at least 5 year battery life at default 10-min logging interval.
