Build a Remote Temperature Sensor with Raspberry Pi and Python – Step‑by‑Step Guide After years of refining this project based on community feedback, this updated guide delivers a ready‑to‑use IoT temperature sensor that runs on any embedded Linux board with Python and 1‑wire support. From a simple

Many home‑automation projects involve building a thermostat from scratch, but what if you already own a programmable thermostat and simply want to record when it turns on or off? This guide explains how to use an optocoupler to safely isolate the 24‑V AC HVAC system from a Raspberry Pi, capture logi

If you need a hassle‑free way to measure temperature without touching the object, the TMP006 infrared sensor is the solution. It reads the heat radiated by an object via its own IR sensor and communicates over a simple I2C bus. This guide walks you through wiring the sensor to a Raspberry Pi or Beag

Measuring Temperature on Raspberry Pi with Maxim 1‑Wire Sensors and DS2482 I2C Bridge Accurate temperature monitoring is essential for many Raspberry Pi projects, from climate control to data logging. The Maxim Integrated 1‑Wire family of sensors, such as the DS18B20, offers a simple, low‑pin soluti

Overview The Raspberry Pi is a compact single‑board computer (SBC) engineered by the Raspberry Pi Foundation in the UK. It runs various ARM‑based Linux distributions and exposes a set of GPIO pins that enable connection to a wide range of external components such as sensors and actuators. Because th

For the full build, see Part 2 (hardware) and Part 3 (software). In this article, we outline the core concepts behind a multichannel data logger that records voltage, current, and temperature at configurable intervals. The goal is to demonstrate that a Raspberry Pi can transition from an educational

Track the temperature and humidity of your home, garage, or small factory from anywhere with this straightforward Raspberry Pi solution. The system streams real‑time data to a web‑based chart, giving you instant insight into your environment. Step 1: The Concept The Raspberry Pi reads temperature a

This guide outlines how to build a lightweight, solar‑powered weather station using a Raspberry Pi and inexpensive sensors. The system records temperature, pressure, humidity, and can be extended to wind speed, direction, UV, and insolation. Step 1: Hardware description Raspberry Pi A+ (any Pi mode

Aquaponics /ˈækwəˈpɒnɨks /, is a food production system that combines conventional aquaculture (raising aquatic animals such as snails, fish, crayfish or prawns in tanks) with hydroponics (cultivating plants in water) in a symbiotic environment. In normal aquaculture, excretions from the animals bei

Welcome! This guide shows you how to connect a DS18B20 digital temperature sensor to a Raspberry Pi 2 and read the room temperature accurately. What You’ll Need DS18B20 waterproof sensor (buy online) 4.7 kΩ pull‑up resistor (yellow‑violet‑red‑gold) Jumper wires Raspberry Pi 2 (any model with GPIO)

Raspberry Pi Temperature & Humidity Network Monitor – DIY Setup Guide Build a reliable, network‑connected temperature and humidity monitor using a Raspberry Pi and an inexpensive sensor. This guide provides a complete parts list, step‑by‑step instructions, and the software needed to capture, st

Over the past couple months I’ve been implementing and building out a monitoring solution for our development and production systems. Since nagios is the most loved / hated monitoring solution I felt obliged to learn how it works. After fighting with user permissions, firewall rules, broken dependen

In this expanded guide we show how to wire and program multiple DS18B20 1‑wire temperature sensors on a Raspberry Pi, a setup ideal for solar water‑heating controllers and any system that requires differential temperature monitoring. The DS18B20 communicates over a single data line using the 1‑wire

On my Raspberry Pi, I mounted a DS18B20 sensor just above the processor to capture the board’s internal temperature. My goal was to map this profile inside the enclosure and present it in a clear visual format. I achieved this by integrating a lightweight Python script, an SQLite3 database, and LabV

Follow these concise steps to turn a $5 I2C temperature sensor into a reliable data logger on a Raspberry Pi. The recorded values are written to the SD card, making them ready for Excel or any data‑analysis tool. Components Raspberry Pi (any model with GPIO) SF‑SEN‑09418 I2C temperature sensor ($5)

The inspiration for my low‑cost thermal imager began in a 2010 physics class when our instructor introduced a single‑point infrared thermometer—commonly known as a pyrometer—into the curriculum. My friend and I seized the opportunity to transform that lone sensor into a full‑field thermal scanner u

Control your home’s temperature from anywhere with a custom NEST‑style thermostat built on a Raspberry Pi, Node‑RED, and ESPurna firmware. Project Overview After juggling multiple work shifts, I found it impossible to manually tweak my old home thermostat each week. I needed a remote solution that

Use a relay‑driven circuit to automatically turn on a fan when the ambient temperature inside your media cabinet exceeds a set threshold. Background While using my media center—Blu‑ray players, gaming consoles, and other electronics—the cabinet started to feel noticeably hot. To address this, I desi

Deploy a scalable IoT solution that couples NodeMCU microcontrollers with DHT22 temperature/humidity sensors to a Raspberry Pi 3 B+ acting as an MQTT broker.
