My goal is to put an always-on, online vibration-based condition monitoring solution in place for our industrial machinery. The system must continuously read and log RPM, displacement, and acceleration, then publish the data to a web dashboard where trending, thresholds, and automatic alerts can be configured in real time. Here is what I already have and what I expect from you: • Sensors & acquisition: I can source standard piezo or MEMS accelerometers and an RPM pickup, but I need guidance on the optimal sensor grade, mounting positions, and a compact DAQ (Raspberry Pi, ESP32, NI cDAQ, or similar—open to your recommendation) capable of simultaneous sampling. • Connectivity & protocol: Data has to leave the shop floor securely. MQTT or REST over Ethernet/...

I need a compact, low-maintenance device that sits beside my underground sump, senses the water level with a float switch, and immediately places an automated voice call to my mobile the moment the tank is full. No batteries or solar panels are required; it can run straight from mains power that already feeds the pump. Here’s the workflow I’m picturing: when I start the motor, your circuitry monitors the float switch. As soon as the switch flips to the “full” position, the controller dials my preset phone number so I can switch the motor off without ever checking the tank. Cost and simplicity matter, so please base the design on readily available components—an inexpensive GSM/4G module or any similarly affordable calling solution is ideal. If you can keep ...
