Temperature-to-period circuit provides linearization of thermistor response

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 var ...

IR HACK TURNS KID’S LAMP INTO TEMP DISPLAY

Sometimes a clever hack of an off-the-shelf product can come courtesy of its dismantling and hardware modification, but at other times the most elegant of hacks can be made without ever turning a screwdriver. [Brian Lough] was given the request by a friend to replicate a commercial child’s night light that changed colour with temperature, and his response was to use an off-the-shelf colour changing kids lig ...

DS18B20 Sensor Based Thermometer with Nokia 5110 LCD display

Hi guys welcome to this tutorial. Today we will be building a simple temperature monitor using the DS18B20 sensor with a Nokia 5110 LCD Display and an Arduino mega. Introduction The DS18B20 digital temperature sensor gives a 9-bit to 12-bit Celsius temperature readings and also has an alarm function with nonvolatile user-programmable upper and lower trigger points. The sensor communicates via the 1-Wire com ...

Nanotechnoloy – Nano coating prevents exploding Li-ion batteries

Lithium-ion batteries are very popular as they’re lightweight and have high energy density. But at the same time, li-ion batteries are very sensitive to overcharge/over discharge. An internal short circuit can cause fire and it may even lead to a violent explosion. Fortunately, nanotechnology found a way to prevent this kind of nightmare. How? let’s discuss: Why Does li-ion Battery Explode? When a device dr ...

MEC extender – and you’re a level higher

We already know, that Switches MEC Unimec switch in up to eight ways and also that they´re available as momentary or alternate (latching). UNIMEC switches feature perhaps only one “disadvantage” – that on the same PCB no other higher components can be used (which would be higher than the switch). If you´re satisfied with the UNIMEC features, but despite that you cannot use them in your application right for ...

Dual-Channel Quadrature Hall-Effect Bipolar Switch Module for Magnetic Encoder

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 detection ap ...
