We are using the Synapse Wireless RF200PD1 in our product. We have an order to supply our product to Japan. We need someone fully familiar with the requirements of obtaining a modular certification of the radio module in Japan, who can shepherd us through the complete process and, if necessary, help prepare the documentation. Most tasks such as preparing the module for certification testing, drawings, etc. we can do, but we need leadership to take the process from beginning to end including selecting the test laboratory, the certification house, etc. Final deliverable is the Japanese certification letter. Successful bidder will demonstrate that a similar certification has been accepted. Japanese consultants or Japanese speaking specialists preferred but not required.

Our product will monitor soil conditions and perform actions based on the measurements. Using an app (Android, iOS, and web based), users can specify triggers for notifications when the soil is outside of the acceptable range (for example, if the temperature is approaching freezing, or soil pH is getting too high). The app will also access the historical data that will be stored via the web to track growth and associate pictures taken. We would like the device to meet the following requirements: Sensors Temperature:range from -40 to 140, accuracy of 1 Humidity: range from 0 to 100% RH accuracy of 2% Barometric pressure Light intensity: range from full daylight to night using photoresistor or solar panel to detect Soil pH: range of 4.5 to 9.5 pH, accurate down to 0.5 Enclosure Waterproof Weatherproof & UV resistant 3"x3"x2" maximum dimensions (not including any probes that would go into the soil) Replaceable battery (AAA or AA size) Data The device should tra...

Job description: seeking a firmware or software developer who has experience with the ESP8266 WiFi module, and who will be responsible for developing a web-enabled acceleration sensor. Project: a WiFi-connected acceleration sensor that streams data to a connected web browser. In this device, the acceleration sensor (ADXL345) is connected by a 3-wire SPI interface to a WiFi module (ESP8266). This WiFi module contains an integrated microcontroller that must be configured to handle html requests, serve resulting data into formatted web pages back to the connected browser and control the sensor based on internal state, logic and html requests. The firmware will be released under the MIT license on our GitHub account or yours (your choice). We will ship hardware to you for both devices and links for all datasheets including the English ESP8266 datasheets, you will need to hook up data/power wires, what is additionally required from you is your own computer for development and a micro-USB ...

This is to hopefully find and start conversations with the right company/individual. We are looking for a firmware person to join our team for a security based project based upon a Zigbee mesh network. Experience in this type of topography required (including pairing, encryption, fail safe messaging, etc.). Also experience in Sharp's memory LCD (2.7") and either custom fonts or Ramtex icon and font package. Our current processor is a Microchip PIC8, which we need to upgrade to either a PIC16 (with enough RAM support to buffer display in memory) or switching all together to an ARM processor (which we would then need to scrap any code written so far). We are open to either a standard work for hire contract, or even possibly an equity/full time position with our company in Wisconsin or Remote. We are really looking to build a solid team of individuals as we launch this project over the next 6 months.

I need to have a Texas Intruments CC2531 Zigbee dongle (USB connection) configured to work with a Beaglebone Black development board running Linux. Drivers for the CC2531 are available for download on the Texas Instruments website. Once set up the proof of working must be turning on and off a supplied Zigbee enabled LED light bulb by means of one of the buttons on-board the Beaglebone. I would supply the Beaglebone Black, CC2531 dongle, Zigbee LED bulb and Texas Instruments CC Debugger. You provide a simple written outline of the steps that were taken for the setup. Please estimate how many hours this will take. Thank you.

Our devices are connected to the Wifi network via Texas Instrument CC3000MOD wifi module and MPS430 as the microprocessor. We are seeking an engineer to transform our C code from cc3000MOD to the new CC3100MOD. We need re-create the initial peering between the Smartphone and the devices while maintaining our app logic. Today the CC3000 uses the "smartconfig" peering method ? we want to mode to the cc3100 AC peering. We would need to go over the connection commands (burned to the MSP) and translate them to work with the cc3100.

Hi I am looking for someone to design the circuit (Schematics and PCB) for an ultrasonic distance sensor. Here is what the project involves: 1. I have attached the specs of the sensor... It's the one you should use. 2. You need to pick one of the two components/designs below and go with that... one is from Analog Devices and one is from TI. ADI:   [obscured]  /media/en/reference-design-documentation/reference-designs/CN0343.pdf TI:   [obscured]  /lit/ds/symlink/pga450-q1.pdf 3. I need to be able to program some simple parameters (and also some filter coefficients) so access to the processor by me is a must. You need to let me know if I need an ICE or development environment, etc. IF the processor is not built into the ultrasonic sensor IC, then I would like to use an Arduino serial port to talk to the sensor board. 4. Power consumption is key... System will be running off of battery
