Control an Arduino via the HM-10 BLE module, from a mobile app on your smartphone Hammad Tariq 2016-08-25 Tutorials In this tutorial, you will learn about controlling a LED using HM-10 BLE module, Arduino and Evothings Studio. I bought a few weeks ago some quite cheap 5 meters RGB LED strips (60 LEDs per meter) on eBay. We will use Adafruit's libraries for DHT11 and DH22 Temperature Humidity Modules. An Arduino microcontroller runs my indoor garden, watering the plants only when they're thirsty, turning on supplemental lights based on how much natural sunlight is received, and alerting me if the temperature drops below a plant-healthy level. There are so many use cases where a temperature humidity sensors can be used to detect potential problem like frozen pipes, broken freezers, malfunctioning air conditioning,. To accurately control process temperature without extensive operator involvement, a temperature control system relies upon a controller,. The Knob sketch This example shows you how you can easily use a potentiometer to move your servo to a specific degree. This project uses a YourDuino RoboRED (or Arduino UNO With Sensor Shield) to monitor the temperatures in a home. Hello there, It's been a while to write here and I came back with a question. Make 1st calibration point by Sodium Chloride An saturation Sodium Chloride (NaCl) in water will create standard 75%RH. Following code is used to upload the temperate sensor data to the thingspeak website. This pocket-sized lab shield has two heaters, two temperature sensors, and an LED. Need to note that I am not super experienced in coding, but worked from the code by @ogiewon ( Announcing the "ST_Anything" Arduino/ThingShield Project ) but seems like I cant create a second or third relay (switch) control. Fixed download links for sketches. BrewBench - Is an Arduino home brewing kettle temperature monitor, controller and notification system. The electrical loads are connected to the control unit through the relay contacts. By using a potentiometer (or any analog sensor), it's possible to directly control your servo with the Arduino in the same way that you'd control a mechanical claw at the arcades. Print() to output the temperature to the IDE serial console. There are three primary components to think about in a PID control loop. virtually any modern microcontroller - then all you need is a bit of code. An Arduino microcontroller runs my indoor garden, watering the plants only when they're thirsty, turning on supplemental lights based on how much natural sunlight is received, and alerting me if the temperature drops below a plant-healthy level. Note that the Arduino SDK only contains a subset of Parse features found in mobile and desktop. Local monitoring of temperature and humidity.
