This project is a LoRa temperature sensor. It uses the RP2040 microcontroller and a SHT31 temperature sensor and also RFM95 for LoRa communication #LoRa #referenceDesign #simple-embedded #raspberrypi #template #reference-design

The Pico-Environment-Sensor gives Raspberry Pi Pico the ability to collect environment data like temperature & humidity, air pressure, ambient light #RaspberryPi #Raspberry #Pi #RPi #Pico #template #project #project-template #hat

This is a project of an energy-efficient temperature and humidity sensor that works via Zigbee #Zigbee #sensor #iot #template #project

PCB that sends ambient temperature and high resolution analog data over a CAN bus for a FSAE electric car. Runs off a Teensy 4.0 and has connection pins for separate external analog sensors.

Weather Station controlled by STM32F031F6P6 MCU. 2x humidity and temperature sensors. USB powered

The AAduino is an wireless Arduino clone the size of an AA battery with Keystone battery terminals rotated 180° to act as positive and negative terminals. It is meant to go inside a 3xAA battery holder creating a very small wireless node. Powered by an ATMega328p, it is fitted with an RFM69CW companion, two DS18B20 temperature sensors and an indicator LED

High-Frequency Full-Bridge Series-Resonant Converter with LM331 and TL431-Based Inverse-Control System for 330–385V HV DC Bus Regulation

The AD8495 K-type thermocouple amplifier from Analog Devices is so easy to use, we documented the whole thing on the back of the tiny PCB. Power the board with 3-18VDC and measure the output voltage on the OUT pin. You can easily convert the voltage to temperature with the following equation: Temperature = (Vout - 1.25) / 0.005 V. So for example, if the voltage is 1.5VDC, the temperature is (1.5 - 1.25) / 0.005 = 50°C with terminal block connections

Fire Alarm circuit project, a thermistor works as the heat sensor. When temperature increases, its resistance decreases, and vice versa. Fire Alarm system works off a 6V-12V regulated power supply. Timer IC NE555 (IC1) is wired as an astable multivibrator oscillating in audio frequency band.
