In this project, we are going to build a Transistor Based Simple Soil Moisture Detector Circuit. In this circuit, we have used an NPN transistor to detect soil moisture. This is very simple and ...

Food and beverage applications make use of a range of sensor technologies. Here’s a brief look at laser displacement sensors. The DS1100 laser-displacement sensor from Cognex, released in March 2013, ...

VCC is the power supply pin of the soil moisture sensor that can be connected to 3.3V or 5V of the supply. But do note that the analog output will vary depending on the provided supply voltage. GND is ...

The MCP9800 is a digital CMOS silicon temperature sensor that provides an accurate digital temperature measurement. Data is converted from an internal diode temperature-sensing element to a digital ...

Characterizing RF power sensors is commonly done using a direct comparison system which employs a resistive RF power splitter with a power standard connected to a power meter. One of the most stable ...

The purpose of this circuit is to animate shop-windows by means of a capacitive sensor placed behind a post-card-like banner. The card is placed against the glass inside the shop-window, and the ...

Going forward, the Kube sensor will be using the ESPEasy (https://github.com/letscontrolit/ESPEasy) project as firmware. The work done by the ESPEasy team is great ...

Dew (condensed moisture) adversely affects the normal performance of sensitive electronic devices. A low-cost circuit for a dew sensor described here can be used to switch off any gadget automatically ...

Abstract: The macroscopic fundamental diagram (MFD) relates space-mean flow density and the speed of an entire network. We present a method for the estimation of a “normalized” MFD with the goal to ...
