This project is an IoT-based Automated Door System that uses a NodeMCU (ESP8266), ultrasonic sensor, servo motor, and the Blynk platform to detect motion and control door opening/closing remotely. ...

Insulin is a peptide hormone secreted from pancreatic beta cells to regulate blood glucose homeostasis. Maturation of active insulin occurs within insulin secretory granules (ISG) by acidification of ...

This project demonstrates an IoT thermometer using the LM35 temperature sensor and NodeMCU v3 Lolin, with real-time temperature data displayed on the Blynk platform. The temperature is measured in ...

Understand why measuring pH in paints is essential, what points to consider while measuring pH and how to measure pH using a Mettler Toledo sensor.

1. Not calibrating your sensor regularly Calibration is the most critical aspect of maintaining your pH sensor. It's the foundation of maintaining your pH sensor's accuracy. Skipping it can lead to ...

Abstract: This paper presents the development of a smart flood monitoring system using Blynk platform as a medium of data transmission. This system is based on two NodeMCU development board integrated ...

Presented here is a polyaniline (PANI)-based pH sensor that can be connected inline to surgical drains to continuously monitor peritoneal secretion in real time for homeostatic changes in pH. During ...

This circuit is an especially simple op-amp application, and is a typical one for a sensor interface where a DC voltage needs to be brought into range of a microcontroller.

An SMU graduate student has developed a miniature pH sensor that can tell when food has spoiled in real time.

Smart IoT-Based Aquarium Monitoring System on Anabas Testudineus Habitat using NodeMcu and Blynk Platform Abstract: In today’s world, many Internets of Things (IoT) system has been developed in the ...
