$15-25 USD / hour

I'm in need for a ESP8266 NodeMCU LUA CP2102 ESP-12E shield with a step down transformer circuit form 24v to two outputs one 12V with a load of 15 Watt max and the second one 5V with a load of 15 Watt max. The 5v will be used to power NodeMCU and the circuits connected to it's gpios. I also need four mosfet transistors with a similar circuit to this link [login to view URL] the voltage in from this circuit will be supplied from the 12V output of our step down transformer circuit, and each one is controlled by a gpio pin from the NodeMCU. I also want to have a DHT22 on board to read temperature and humidity from one of the gpio pins as well. I also want to have four three pole ph2.0 connector the first one will be ground then vcc and a gpio pin for read or write and I want them to operate at 5V logic. Lastly I need two more of the three pole ph2.0 connector with the same wiring to operate at 3.3V. I know I said lastly but I just remembered that I will need an antenna on board as well. Please let me know your rate for this project. I also wanted to let you know that this is the first phase of the project there are two more phases.

HOME AUTOMATION USING IOT: IOT is now one of most trending words / technologies. The purpose of the project is to build a product which can help the user control any electronics device remotely when connect to internet. The existing electric switch system is replaced by capacitive ‘touch’ switches which enable the user to control the appliances manually as well as by using an Android app. In order to achieve this, a touch panel is interfaced to the microcontroller on transmitter side which sends ON/OFF commands, by an Android app, to the receiver where loads are connected Technology Expertise: Embedded ‘C’, Wi-Fi communication, Android Mobile application, PCB design and fabrication, Involved in mechanical structure design, Relays, NodeMCU controller SMART BAND: In today’s scenario, we find females working for long time equally with men at offices. It always has been a concern of security until they reach home safely. We even find the missing cases being recorded at rush areas like markets, exhibitions etc. Smart Band can be efficiently used for continuous tracking and acts as trigger for immediate support. Technology Expertise: Embedded ‘C’, GSM and GPS, Mechanical design to easy wear, Battery selection

Hello, What Antenna you need? I have many years of experience in the development of electronics. I can prepare all the technical documentation for mass production. Also fulfill all conditions for certification CE, FCC and ROHS compliance. PCB layout and Circuit Design I develop compact solutions, and use the new component base and surface mount components. I can show examples, add me to Skype - ivanchuba or email. I'm calculating the minimum cost of BOM at the time of development. Also I can make the necessary number of industrial prototypes. Best regards
