Previously we talked about this sensor and made an example of how to use it you can see here. But if you want to create your own circuit for measuring different values of maximum power, you can use this guide to help you to assign the values of R1 and RBURDEN.
The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU (Micro Controller Unit) capability. This small module allows microcontrollers to connect to a Wi-Fi network and make simple TCP/IP connections using Hayes-style commands. The low price and the fact that there were very few external components on the module attracted many hackers to explore the module. This chip is perfect to start a new IOT (Internet of Things) project.
Measure distances using ultrasonic sensors with Arduino is very common, but not only distances are measured, are also used in robotics for obstacle detection. If you are thinking of using one of these modules in your projects then we explain how the HC-SR04 sensor works. Continue reading
Continuing with sensors that can be used in aquaponics, hydroponics systems or automatic outdoor plant care, we will explain how to use a water level sensor to control the amount of water we have in a tank. The same sensor can also be used to detect if it is raining.
If you are building a system to irrigate your plants automatically monitoring the soil moisture is more reliable than set watering cycles, so that only watering when your plants need, avoiding problems by overwatering. Here we will explain how to use one of these soil moisture sensors to Arduino.
If you are automating a hydroponic system, aquaponic or just an aquarium, you know that have monitored the water temperature is critical to your system stays in top condition. Among the variety of submersibles temperature probes find a solution based on digital DS18B20 sensor. Here we explain how you can use with Arduino.
