We took an advanced Gas Sensor and added our secret sauce: we made it into a Smart Gas Alert. Myspool Gas Alert gives you all the functionality of a first rate Gas Sensor: it detects explosive gases such as natural gas (methane) and LPG (propane). It sounds a loud alarm, has a display that shows detected gas concentration, and has been extensively tested.
Like all MySpool devices, Gas Alert is also a smart device that sends out an alert when Gas is detected by its sensor. That alert is a message, either via email or text, or both. Optionally, this device can also send you pushbullet notifications. Gas Alert is configured to use your WiFi. The setup takes a few minutes with a smart phone or a laptop. 
There are no fees for using Myspool Gas Alert for any kind of alert notifications. One requirement for the Gas Alert location is that a WiFi network is available to access Myspool cloud servers.
