Solar-powered outdoor weather station with PC logging and graphs

Posted on by 2 comments

I have always enjoyed reading/doing projects that involve sensing various environmental parameters and recording them. This Solar-powered outdoor weather station built upon the Arduino platform measures the ambient temperature, humidity and barometric pressure, and send these parameters to a PC using XBee RF modules. The measurements are recorded on the PC and presented in nice charts showing their temporal trends.

The beauty of this project is that the outdoor module is fully powered through a Lipo battery which is charged through a solar panel. Sensors used in this project are DHT22 for temperature and relative humidity measurements, and BMP0805 for measuring barometric pressure.

Microchip introduces new temperature sensors with 1.8V SMBus and I2C™ Interface

Microchip Technology Inc. has announced a new six-member family of temperature sensor ICs called the EMC118X.  This is the world’s first family of temp sensors with 1.8V SMBus and I2C™ communications, which is required for interfacing to the latest generation of smartphone, tablet and PC chipsets.  Additionally, this integrated low-voltage I/O support reduces cost and board space because it is accomplished without an external voltage level shifter.  These are also the first temp sensors to use an advanced sample-frequency-hopping filter, which enables temperature-monitoring traces of up to 8 inches in noisy environments with accurate readings.  The EMC118X family serves a broad range of applications in the mobile, commercial and embedded computing markets, by combining the above features with options for dual, triple and quad temperature monitoring, along with hardwired system-shutdown settings that can’t be overridden by software.
