Liquid or powder detector works with non-metallic containers: continuously monitors liquid level and sends text and email alerts when high or low thresholds are exceeded.

High quality custom sensor comes with a 5 ft cable. It can be configured to detect the presence or absence of liquids to send alerts. Works with non-metallic containers, such as plastic, glass, ceramics, and other containers. The sensing distance (container wall thickness) can be up to 15mm, 6 mm recommended. Liquid, powder, and particulate matter can be detected. Can also be used as liquid flow sensor in a pipe.

Take advantage of available A/C power to receive water level change notifications: sensor triggers the device when it detects the presence (or absence, depending on your requirements) of liquid or powder behind a container wall or a pipe, and transmits an alert to our cloud servers. That alert then gets sent as a text message, email, or a push notification. 

Non-contact liquid level alert comes with a waterproof sensor with a 5 ft wire and a double sided tape for container wall installation. Send alerts when liquid levels rise or fall, depending on your use case.

• Email and text message notification when liquid or powder level change is detected. All services are free.
• A/C powered wireless liquid level detector using your WiFi, no app to install and no hub is required. Perfect as a standalone high or low water alarm.
• Works with plastic, glass, ceramic, pvc and most non-metallic containers.
• Alert is sent if the water rise is detected. Use the jumper inside marked Select to change the sensing behavior and use this device to detect low water levels in aquariums, ponds, and storage tanks.
• Each MySpool plugin device is monitored by a free Central Monitoring Service. If a device fails two daily check-ins in a row, an email will be sent urging to investigate power and WiFi availability. 

Note: this capacitive sensor can sense liquid, powder, or even your hand. It can sense level, flow, or powder quantity changes.  The number of applications for this device is limited only by your imagination.
There is a limit of 50 SMS messages per month per device. The number of email or push notifications is not limited.
