photoresistor

(OBSOLETE) ESP MQTT JSON Multisensor for Home Assistant. Supported sensors include the TEMT6000 light, AM312 PIR, DHT22 temperature/humidity sensors. RGB led supports flash, fade, and transition. Over-The-Air (OTA) uploading, too!

Sensor Node On Steroids

PCB for simple analog solar tracker

Example projects that I created based on components received with Adafruit's Adabox001.

control system which can monitor and improve the conditions of temperature, humidity and light intensity for a given particular plant

Using the FreeRTOS Queue, read the ADC data from the voltage divider with a photoresistor and control the LED with PWM.

Analog light sensor to night power up LED garland. For Camping use.

A library for a microcontroller that corrects time offset by measuring the light level against a computed daylight curve.

Passive Infrared sensor and photoresistor controlled relay

A short, simple tutorial for using Light Dependent Resistors with RNBO on the Raspberry Pi

Arduino-compatibile ESP8266 module's firmware for WiFi connection, photoresistor and servo in smart-home system

Sistema con PIC18F2550 utilizando sensores de temperatura, humedad, gas, presencia y luminosidad, además de la implementación digital de un osciloscopio con 2 canales utilizando C# y C

Connection to Arduino relay songle srd-05vdc-sl-c 10a and photoresistor

Arduino automatic light control using LDR photoresistor - turns LED on/off based on ambient light threshold

Automatic toilet exhaust fan controller based on CH32V003. The fan starts after the light is turned off and runs for a time proportional to the light usage duration. Supports IR remote control.
