I am completely new to LabVIEW, have very little programming experience, and need some assistance or points in the right direction. I am creating an automated loop that utilizes a bluetooth-connected pH probe (Go Direct® pH Sensor - Vernier) to provide a real-time pH value in LabVIEW. Depending on this value, i.e. if the live pH dips below 7.2, the program will trigger an Alladin Syringe pump (SyringePump.com: NE-4000 Programmable 2 Channel Syringe Pump) to administer a specific volume of pH buffer fluid, bringing the pH back to 7.2. No drivers are needed for the syringe pump. I believe a driver may be needed for the pH probe.
Any help would be highly appreciated!

First, you need to know the format in which your pH probe sends data over Bluetooth.
LabVIEW comes with a Bluetooth palette, you could leverage it,
Next, your Syringe Pump has an RS232 port, you can connect it to the computer using a USB-RS232 cable, check if they supply any LabVIEW driver, if not, once you understand the commands you need to use, you can develop your own driver - this is a good article to understand VISA communication https://labviewwiki.org/wiki/VIWeek_2020/Proper_way_to_communicate_over_serial

I just send you an email with all details for our system.
