Wireless PICAXE-based water tank level sensor

Over the last few months I have prototyped and built a water tank level sensor for my 9000L rain water tank. The design is based entirely on Silicon Chip’s PIC-Based Water-Tank Level Meter, but instead of programming PICs, I prototyped using an arduino, and built the final version using PICAXE microcontrollers. The sensor consists of two components, each housed separately and joined by shielded cable. Press ...

The world’s tiniest temperature sensor is powered by radio waves

Researchers at TU/e have developed a very tiny wireless temperature sensor that is powered in a very special way: from the radio waves that are part of the sensor’s wireless network. This means that the sensor needs not even a single wire, nor a battery that would have to be replaced. The arrival of such sensors is an important development on route towards smart buildings, for instance. But the applications ...

Humidity and temperature measurements with Sensirion’s SHT1x/SHT7x sensors using PIC18F2550 (Part 1)

Temperature and relative humidity are two very important ambient parameters that are directly related to human comfort. Sometimes, you may be able to bear higher temperatures, if there is a lower relative humidity, such as in hot and dry desert-like environment. However, being in a humid place with not very high temperature may make you feel like melting. This is because if there is high relative humidity, ...

LED fireflies prototype using PIC12f683 microcontroller

LED fireflies prototype hello all, heres an attempt i made at something like an LED throwie..the problem (for me) with led throwies is that they just consume their battery, and produce light.. but they could be better at doing both.. first you have to accept the premise that your willing to spend a bit more for the tradeoff.. the inspiration for this came from some of my other projects, and of course the "L ...
