4-channel Wi-Fi voltage logger. Early access list is now live. Link in Bio.
Been building a Wi-Fi voltage logger/data logger from scratch over the last little while and it’s finally starting to feel like a real product instead of just another bench prototype ⚡📈
Current features:
4-channel voltage monitoring
Real-time live graphing
Save + recall test sessions
ESP32 + ADS1115 based
Wi-Fi setup through captive portal
Data saved directly to PC
Long-term voltage testing/logging
Status monitoring + reconnect handling
Right now I’m mainly focused on improving graph responsiveness, signal sensitivity, firmware cleanup, enclosure design, and overall usability.
The whole goal is basically: “industrial-style voltage monitoring without stupid expensive hardware”
I’m documenting the development process as I go because honestly I think seeing the raw prototyping/debugging side is interesting too — PCB design, firmware, enclosures, RF/electronics lab stuff, etc.
Would genuinely love feedback from people who actually do embedded/electronics/test engineering work:
Features you’d want
Sample rate expectations
UI ideas
Logging/export features
Things that annoy you about existing tools
Also started an email list for updates/early access because people were already asking about buying one: voltsense.carrd.co
