Temperature and Humidity Alert with text message and email notifications
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 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
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.
