Story The idea There are many beautiful and interesting projects in here, things well done who have inspired me to build my own project. I’ve always loved & liked the idea of monitoring and controlling things and the smart home concept is already a well known concept. The idea of this project will encourage people […]

I live in Canada, in a peaceful area. There are still some bad things that could happen and have a negative impact on my property. Here are a few examples: Fire A friend of mine has lost his house just because the dishwasher was broken. As per local regulations, we have smoke detectors on all floors,

The A1230 is a dual-channel, bipolar switch with two Hall-effect sensing elements, each providing a separate digital output for speed and direction signal processing capability. The Hall elements are photo lithographically aligned to better than 1 µm. maintaining accurate mechanical location between the two active Hall elements eliminates the major manufacturing hurdle encountered in fine-pitch

Temperature/Force Sensor Sample This sample uses SPI communication. A temperature/force sensor is connected to a ADC, then ADC is connected to raspberry Pi2 through SPI Pins. Raspberry Pi2 reads the sensor analog input data and output it to the screen. This is basically a simplified version of Potentiometer sensor sample, which has a LED light

ZigBee Primer A ZigBee PAN (personal area network) is a self-organizing series of modems that communicate using the same protocol (based on the IEEE 802.15.4 standard). Individual modems are configured to play a specific role within the network. Coordinators establish and organize the network (there is only ever one coordinator in a network). End Devices

The simple current-limiting load switch shown in Figure 1 will be familiar to most readers. In this circuit, a high level signal applied to the input switches on MOSFET Q2, which energizes the load. The load current is limited by negative feedback applied via Q1. In most applications, the current flowing via R2 into Q1’s

The app allows you to manage traditional air conditioners that are controlled through infrared remotes. Designed for the office environment, the app relies on the ambient brightness (measured by Tibbit #28) to determine whether the aircon should be running or not. In the office setting, no lights = no people = no need for the

Designers often use thermistors rather than other temperature sensors because thermistors offer high sensitivity, compactness, low cost, and small time constants. But most thermistors’ resistance-versus-temperature characteristics are highly nonlinear and need correction for applications that require a linear response. Using a thermistor as a sensor, the simple circuit in Figure 1 provides a time period
