I need someone who can make a project with the help of pic micro controller [url removed, login to view] will use a smoke sensor and temperature sensor and detect the fire and turn the alarm on. urgent required. only serious bidder bid.
we are producer of IOT security devices and like to enhance the products by ISM Band Temperature sensor connected to our IOT devices. Design and layout of 868 MHz Temperature/humidity sensor unit including layout and firmware. Battery operated 2 year with CR2032 (soldered). Sending every 7 s Data. Data acknowledge (so need transmitter) Temperature sensor -20°C + 70°C + Humidity sensor Capable to be calibrated by software. Expandable to enable additional 3d acceleration sensor to be integrated on board as option. Option for PIR Sensor with light detection sensor. Sensor is connecting to IOT Modul. Self connecting. Sensor has UID. Up to handle 128 units with one IOT device (non collision support by statistic modulation duty cycle). low power microcontroller STM + ISM Transmitter + sheet metal antenna. Requirements: electrical engineer with experience in microcontroller and ISM Band RF design + firmware. preferred: experience in battery operated device development for low power design TIMEFRAME: ~ 1 month circuit + PCB design + 2 month firmware + Test + support industrialisation.
This Proposal is for the development of a proof of concept model of a device (6X) that will connect to and measure the power output from a solar panel and report the energy generated to cloud based services for collection, analysis, and potentially providing rewards for generating the energy.
Actualmente tengo un circuito acabado y funcional GPS, pero la señal recibida es muy débil debido a un mal diseño , me gustaría que retocaras el archivo gerber para reparar este fallo o incluso se colocara un circuito amplificador
Hallo we have a pcb board, which should be ok with RFID. Your new updated board will handle RFID and BLE together. Your new Antenna should be a combi antenna. We need circuit design + Antena code. Programming needed to be in atmel studio. We will use same board structure and need to add functionality of program inside. So your job is to add adjust RFID and Implement BLE code and Antenna Design. Please contact me if you have experience in Rfid / BLE setup pcb. We have full code description of total functionality. You have to be able to start from coming week. Im off mainly tuesday to thursday. Budget and Quality depend together so 5 USD is no relevant figure. Thanks for interest
I am doing a project the in my home and I am using the attached diagram. That uses long wires to check a status (ON or OFF), Is this diagram correct? if you have done some industry products that uses such diagram then you can take this project, show some examples you have done before.
Design the mechanical housing to fit the size of 1W, 5V solar panel (150X80X22mm). Rectangular in shape, with sloping on one side where there is a handle. Material per your recommendation, quality. Features: Solar panel, PCB mounted inside with mounting screws, three LEDs openings, external access for Mini USB; USB, and TRS jack Solid works SW?

A tailored PCB required for a small space. Dimensions of space: Diameter 5.5mm, Length upto 60mm. PCB required to operate a Micro-Buzzer from a 9v Power Source. Ideally non-polarised. Designers will have to consider component sizes and dimensions as well as circuit layout.
We are looking for a RF engineer to help us with a cellular Cat M1 application (700 LTE). We would like to use an off-the-shelf antenna and interface it into our smaller PCB. We need a RF engineer to analyze the ground plane situation and advise us how to improve the performance of the antenna, specifically efficiency. It would be best if you had RF simulation software and experience and/or antenna design experience. We will consider designing our own antenna, if required. It would be ideal if you had access to an anechoic chamber for performing tuning and testing of our prototypes. This is a fairly simple RF task that could lead into more complex designs such as a custom antenna. Please have experience in this area of RF including tuning, ground plane analysis, testing and ideally antenna design.
The purpose of this project is to create a circuit-accurate recreation of a MiniLED display array, using off-the shelf (macro-size) components. This display will feature a large array of monochromatic (blue) pixels (SMD LED's) packed tightly as possible in a 5" and/or 11" diagonal 16:9 widescreen aspect ratios, on PCB. Your work will be invaluable for use by engineers, developers, and in technology demonstrations. Your analog design skills and basic coding are both going to be important here. This task Design a PCB to combine and stack Arduino and multiple sub-components function boards into a robust demo unit. This will support power measurement and portable operation on Battery, as well as USB Cable / AC-power. The major components : - Arduino (Mega) for managing image memory and driving the array - Blue LED array - Image memory - Pixel Storage Cap & Comparator array - Decoder Shift Register - DAC Array - Triangle wave generator - Total Display Array power - Battery - AC-Power/Charging port - Bluetooth or USB interface for downloading images The components must be all SMD, low-profile and readily available eg. in-stock on Amazon, Digikey, Mouser Contractor will : - Develop the software for downloading images to the demo board from PC/Mac - Design a PCB board to host the sub-component boards in a robust assembly - Provide the PCB layout and circuit diagrams - Have the PCB manufactured for 10pcs (invoiced separately, not included in project) - Purchase the components (invoiced separately, not included in project) - Assemble multiple units of the boards + modules - Test the assemblies to verify functionality - Flash the units with the latest firmware, including support for all of the functionality current & planned per the Trello SmartCard Proto project - Post all source-code and firmware binaries, and update tools to ensure continued operation and development All as described and co-ordinated per Milestones maintained in Trello
I am interested in getting developers to work on lowRISC to help accelerate the process of getting an open source silicon chip available. We would subsequently use this chip in consumer devices, such as laptops. I would like to discuss this with you. Thanks! -Jeff [Removed by Freelancer.com Admin - please see Section 13 of our Terms and Conditions]
need minature circuit board design that uses a recorded sound chip (like for greeting cards), plays short track every 5 to 10 minutes on a small flat piezo speaker using solar power and a small battery for a 6 month life. need on-off switch and LED indicator
