Πληρωμή κατά την παράδοση
I need to study small animals (chicken and other birds) biometrics. I need a small device to be used with this animals, heart beat up to 450 bpm and oximetry around 80%. The device should work for a month and send the data to a bluetooth device, the "server" may be also programmed to receive the data (*.csv is fine). Each device should have a unique number, and they must work with others. Data may be send directly or stored in the device. Max 2x2x0.5cm and 25 g (including battery). The data bmp/ox should be acquired 4 times every day for at least 1 month.

Dear Sir, I am an experienced embedded system developer. I have expertise in designing extremely low power and low profile electronic circuits as well as programing microchips for Bluetooth low power application. I have found, a millimeter-scale lithium-ion battery for autonomous applications. That will be ideal solution for your project. However, I would like to consider about an idea of designing a device, which can be charged from RF signal from Bluetooth client device. I would like to discuss more details about the project before the final design. Best Wishes

Dear, We are a Argentinian company that have more than 7 years of experience in embedded programming, PCB's design with KiCad and industrial electronic systems implementation. And we have alliances with local and overseas partners for mass production. We can make the PCB and schematic design using KiKad and PCB assembly (We have SMT and soldering lines for small quantities prototype productions). We have a lot of experience in low power applications, cellphone chargers, battery chargers, motor control, H bridges (1 and 3 phases), etc. We can develop the complete solution, mechanical design and drawings, PCB design, PCB assembly, firmware programming, and machine assembly. This Bid proposal is only for PCB (schematics, PCB layout, and Gerbers). Programming, KiCad is an open source software suite for Electronic Design Automation (EDA). The programs handle Schematic Capture, and PCB Layout with Gerber output. The suite runs on Windows, Linux and macOS and is licensed under GNU GPL v3. Thanks you Leonel Caraccioli OpenMolo
