Lepton Low operating power - 150 mW (operating), 650 mW (during shutter event), 5 mW (standby).Note: If it worked for long hours, Lepton will heat up a little. The effective image generate by the Lepton sensor is 160×120, but you can process the image thru program and display a different resolution. tCam-Mini costs $64.99 and Lepton 3.5 costs $199.00 at GroupGets store.FLIR features the latest FLIR Lepton 3.0 longwave-infrared (LWIR) camera core, get two times the resolution and 4x the pixels of the previous 2.x generationįLIR is covered by a 3D printing case, makes it a perfect functional bottom for non-contact temperature measurement, compatible with M5Core and can be controlled via I2C protocol. More information on Lepton 3.5 and compatible development hardware can be found at this GroupGets post. Mechanical Interface: 32–pin socket interface to standard Molex® socket.Control Interface: CCI (I2C-like), CMOS IO Voltage Levels.Output Format: User-selectable 14-bit, 8-bit (AGC applied), or 24-bit RGB (AGC and colorization applied).Pixel Arrangement: 160 (H) × 120 (V) active pixels with progressive scan.

Radiometry software features for temp measurement including per pixel and frame radiometric output (TLinear) and Spotmeter.Low Gain Mode: Greater of +/- 10☌ or 10% (typical).High Gain Mode: Greater of +/- 5☌ or 5% (typical).Image Optimization: Integrated digital thermal image processing functions, including automatic thermal environment compensation, noise filters, non-uniformity correction, and gain control.Thermal Sensitivity: Field of View: 57° (nominal) HFOV, 71° diagonal (f/1.1 silicon doublet).Input Clock: 25-MHz nominal, CMOS IO Voltage Levels.
Sensor Technology: Uncooled VOx microbolometer.This is the type of high contrast RGB thermal images we are familiar of seeing.įlir Lepton 3.5 Specifications of Lepton 3.5 This image is then added with false colors of the RGB range so that the gradients of temperatures are better perceivable to us. The resulting image is typically a monochrome image. Unlike that, each pixel in a thermal imaging camera captures IR intensity and is calibrated to output the temperature of the object it is seeing. The intensity values are converted to a digital format to create a digital image that can be displayed on an RGB display. Ordinary camera modules measure the intensity of three ranges of wavelengths namely Red, Green and Blue (RGB). The wavelength of light in this range falls between 8 µm to 14 µm. It functions just like a camera module inside a smartphone but captures light in the Infrared (IR) region of the electromagnetic spectrum. TCam-Mini Thermal Imaging Module in action Infrared Radiometry and Lepton 3.5įlir Lepton 3.5 is a radiometric capable Long-Wave Infrared (LWIR) camera module from the Lepton series. You can buy tCam-Mini and camera modules from GroupGets store. You have to buy the camera module separately when you buy the tCam-Mini. The tCam-Mini is a carrier and processor board that has a compatible socket for Lepton 3.5. It has a form-factor and mechanical interface to be easily installed onto a side-contact socket. Lepton 3.5 has 19,200 (160×120) pixels that can capture IR radiation in the temperature equivalent range of -10˚ to +400˚C. The firmware is written using ESP-IDF and can be flashed to the module via USB. The project is completely open source and the hardware and software files can be downloaded from Dan’s GitHub repository. As the name suggests, tCam-Mini is a smaller subset of the fully featured design called tCam which is currently under development.
The project was successfully funded and the campaign ended on 07 April 2021. tCam-Mini was crowd funded and launched through Hackster Launch programme by Hackster.io and GroupGets. The fully open source project is based on Espressif’s ESP32 Wi-Fi module and FLIR‘s thermal imaging camera module Lepton 3.5. TCam-Mini is a wireless thermal imaging camera designed by Dan Julio from Colorado, USA.
