Adding sensors to your Arduino opens up a whole new world of exciting projects. ... Measuring the pH level of a water source can give you a range of information about the liquid.

Insert the 2 probes (wires, pcb) in the dry soil and measure the resistance value and then pour water and measure it again. Use a mid value for the resistor (eg: 50kΩ for 100kΩ in dry soil and 10kΩ in ...

The soil moisture sensor module , built around the LM393 comparator, gives an active-low (L) level output when the soil is dry (determined by a pre-setted threshold value). This digital output (wet ...

My shed is mostly done, which means I'm moving onto other projects that look a lot like landscaping. Lawns, gardens, etc. I want to be efficient in my watering, and potentially even lazy and have ...

Ever wanted to measure soil moisture? Common “soil moisture meter module arduino raspberry compatible free shipping” PCBs might deceive you with their ascetic looks. Today, [Raphael (@r… ...

My soil-moisture reading was in the low 700s in soil that had around 30 percent moisture (according to a comparison with a commercial soil-moisture sensor), and 661 in a drier pot.

K-State researchers have received $2M to develop sensors that can detect nutrients, chemical compounds, soil microbiomes and greenhouse gases in soil.

That’s right, these parking sensors are powered by an Arduino board, and the only extra components that were used in the project are a HC SR04 ultrasonic sensor, an active buzzer, and jumper wires.

Using an Arduino shield extension board together with a NB-IoT BLE Gateway and BLE Sensor Probe the open source system allows you to connect to 25 ...
