One of the most commonly used medical instruments nowadays is the thermometer. The thermometer is used to monitor or measure the body temperature of a sick person. The idea of creating a thermometer started from a device called thermoscope, a thermometer without a scale. Several inventors developed it until Sir Thomas Allbutt invented the first […]

Even the actual series like SHT1x and SHT2x belong to a top in this segment. Forthcoming series SHT3x (SHT30, SHT31 and soon also SHT35) addresses mainly those of you, requiring maximum accuracy even in limit values (humidity below 10% and above 90%), miniature dimensions and ultra low power consumption. So a main difference of a

EEPROM is useful for storing long term data such as data logger information and this PIC microcontroller EEPROM project saves the temperature from an LM35DZ IC to the PIC’s internal long term data storage area. The project follows on from the last project using the virtually the same hardware. It stores temperature readings internally at
This project describes an easy and inexpensive way of adding a digital thermometer and data logging feature to a PC. It involves a PIC microcontroller that gets the surrounding temperature information from the Microchip MCP9701 sensor, and sends it to a PC through an USB-UART interface. The USB port of the PC is also used

An automatic temperature control system has the ability to monitor and control the temperature of a specified space without human intervention. The primary purpose is to manage the temperature of a given area based on settings by a user of the system. This project uses a PIC microcontroller to automatically control the temperature of an

The SiT5003 is the most flexible LVCMOS/LVTTL/HCMOS compatible, ultra-stable MEMS VCTCXO (Voltage Controlled, Temperature Compensated Oscillator) solution in the market. This device supports any combination of the following features: frequency (1 – 80MHz), voltage (1.8V, 2.5V-3.3V), stability (±0.5PPM), pull range (±12.5PPM to ±50PPM) and 4-pin packages (3225, 5032, 7050). It provides superior shock and vibration

Some notes: 1. The C3 can be omitted, its purpose was to filter noises picked up by connecting cable between board and sensing transistor, but as the transistor is mounted on the board it become unnecessary. 2. R8 is optional and is for reducing the fan speed. Its value must be calculated according the fan
