High-quality ambient temperature and humidity sensors can be operated in two modes.  One  mode sends alerts when temperature or humidity goes above or below your thresholds. And the second mode allows you to send data to a ThingSpeak channel for display and analysis. See here for directions on how to setup this free data channel. A display of the last 24-hour temperature and humidity measurements is also available on myspool.com after you login, under MY DEVICES.

The two sensors are connected to the communications module by a 2 foot thin cable. That allows the user to place sensors in a refrigerator or in a data cabinet, for example. By leaving the communications module outside, a good connection with WiFi can be ensured.  This device comes with an extra long flat 6 ft power cord.

The range of the temperature sensor is -10°C to +80°C  (14°F to 176°F).

Multiple (up to 5) email addresses can be added to receive temperature and humidity alerts.  All or some of them can be used  to receive text notifications. See General FAQ  for details.

Email messages are limited to one per minute per sensor.

Each MySpool temperature and humidity alert is monitored by a free Central Monitoring Service. If a device fails two daily check-ins in a row, an email is sent that there is an issue. Another notification is sent when that device comes back online.

All MySpool services are free.

High-quality waterproof temperature sensor can be used to measure both air and liquid temperatures. It can operate in two modes.  One  mode sends alerts when temperature goes above or below your thresholds. And the second mode allows you to send data to a ThingSpeak channel for display and analysis. See here for directions on how to setup this free data channel.  

Temperature Alert comes with an extra long flat 6 ft power cord. Its high quality  temperature sensor has a temperature range from -55°C to +125°C (-67°F to +257°F), with accuracy of 0.5°C over recommended range of -10°C to +85°C. All readings outside this range are ignored: -30°C to +105°C or -22°F to +221°F

Dual Sensor Water and Temperature (WT) Edition:  enjoy all the benefits of the Rugged MySpool Water Alert with an added Waterproof Temperature sensor.

The added high-quality waterproof temperature sensor can be operated in two modes.  One  mode sends alerts when temperature goes above or below your thresholds. And the second mode allows you to send data to a ThingSpeak channel for display and analysis. See here for directions on how to setup this free data channel.
The enclosure of the Water  and Temperature Alert will support 300 lbs. You can step on it in the dark and not worry about destroying it. It is also more water resistant than a standard Water Alert enclosure. It has mounting holes for screws and a gasket to provide better protection to the smart electronics inside.  

Water and Temperature Alert comes with an extra long 6 ft power cord and two hardened sensors:  a water sensor with a 5 ft wire and a temperature sensor with a 3ft wire. High quality moisture sensor has a nickel plated surface for corrosion resistance. It is designed for multi use: just wipe it dry and use it again. High quality waterproof temperature sensor has a temperature range from -55°C to +125°C (-67°F to +257°F), with accuracy of 0.5°C over recommended range of -10°C to +85°C. All readings outside this range are ignored: -30°C to +105°C or -22°F to +221°F

Note: Water alerts can be sent as a text message, email, pushbullet or any combination of the three. Temperature alerts are sent only as email or pushbullet notifications.
