Trasmitting data from pressure transducer to phone/web server

Question

I am creating a 24 hour blood pressure monitor that is designed to be sleek and comfortable, I have decided on The Honey Well Series NBP AN transducer (see more info here: Basic Board Mount Pressure Sensors, p13) I want to connect that to a board so that the data can be transmitted wirelessly, or by cable to a phone or computer, how would I go about doing that?

Answer 1

Since your sensor has an analog output. If your comfortable with prototype level work, get an Arduino that has analog inputs then connect a bluetooth module such as the HC-05. Then, you can transmit that data using some code that I wrote to send multiple sensors in columns. You can modify this code to your needs.

sending sensor data - serial over bluetooth

Your next task would be to write software, but you can view this data on a PC or phone using a terminal program like Teraterm.

Answer 2

One such way transfer data is to use a Internet of Things (IOT) platform. You will need at minimum a microcontroller and wifi module. Currently some semiconductor vendors produce a both the microcontroller in a system on a chip (SOC) form factor. Either way you can access pressure sensor data via the microcontoller use the wifi connection to transmit the data to the web. Take a look at following two option from Texas Instruments.

• Internet-of-Things Solution for MCU Applications CC3100 + TIVA TM4C123
• SimpleLink Wi-Fi CC3200 LaunchPad (Both microcontroller and Wifi in one package)

There are also other vendor that offer similar solutions. I will listed few below under references.

There are other options, microcontroller + cellular, Microcontroller + BLE, BLE to smartphone + internet.

I suggest that you do a little research to narrow down the options. At which point you can post a question specific to your option so detail solution can be provided.
