The Hema-Imager is an affordable thermal imager that pairs with your smart device to help you diagnose common household problems

The Hema-Imager is a wireless thermopile-based imaging device that is not only compatible with nearly any smart device but has better temperature accuracy (0.2F), wider temperature range (-50F - 450F) and better sensor angular resolution (0.61 angular degrees) than the closest affordable competition. Our apps can be used to display and store thermal images only or to display and store combined thermal and optical camera images, with adjustable thresholds and colormaps.

A few key elements of the Hema-Imager require further development (listed below in Development Timeline). The hardware, including electronics, case and firmware, is developed, with a manufacturing plan in place. A beta version of the Android and alpha version of the iOS application software have been developed and are being tested, but require further development for consumers.

Product Specs:

• 64x62 thermopile array with integrated optics. 
• Best sensor resolution at this price at 0.61 degree angular resolution
• No non-uniformity correction needed with thermopile technology
• Frame rate up to the ITAR-TASS regulations limit of 9 frames per second to any fully Bluetooth- or WiFi-capable device.
• Low power consumption and 850 mAhr battery provides up to 8 hours of continuous use without charging, or over a month if just using for 10 minutes daily.
• Android application for smartphone or tablet
• iOS application for iPhone and iPad
• Python & OpenCV application for windows & linux desktop
• App or button-driven laser pointer and online temperature display aligned to center of field of view with 0.2 deg Fahrenheit accuracy
• Thermal measurement range: -50F to 450F

Benefits:

• Use with any smart device (see Attachment and Thermal-to-camera calibration)
• Stores securely in an ultralow power mode, wakes up with a single button press
• Quick-connect with your smartphone or computer within seconds
• Store thermal images with various colormaps or transparent overlay on camera images
• Store video stream of either thermal or transparent overlay on camera video
• Can be used at up to 20m (Bluetooth) or 100m (WiFi) distance from your smartphone or computer
• Standby alarm mode: set it up on a scene, capture, then set an alarm on a selected feature and walk away
