Analog pH sensors output a small analog voltage signal, generally in the millivolt range, that corresponds linearly to the pH value. This voltage signal is continuous and varies smoothly as the pH ...

As I've experimented and played with a lot of different sensors, I've discovered that these basic devices can be built for ...

If you're looking to take the plunge into the world of ESP32 devices, then here's a basic overview of what you need to know.

Here we report on a bioresorbable fluorescence sensor for in vivo pH monitoring. The sensor leverages a nanometer-thick multilayer stack of polyelectrolytes labelled with a pH-insensitive fluorophore ...

An LD2410 presence sensor that was working perfectly for weeks on an ESP8266 stopped providing data after a recent ESPHome update. The ESPHome device connects to Wi-Fi and Home Assistant, and all ...

An iridium oxide-based electrical pH sensor that is suitable to be embedded in an electronic bandage for skin monitoring has been developed. The electrical pH sensor does not entail high-temperature ...
