TEMP&HUM 10 CLICK
PID: MIKROE3342
Weight: 23 g
Temp&Hum 10 Click is a smart temperature an d humidity sensing Click board, aimed towards IoT
applications, due to its extremel y small size and very low power consumption. It can measure a wide
range of temper ature an d relative humidity (RH) valu es w i th hi gh accuracy. The sensor used on this
Click board offers the complete measurement syst em: capacitiv e RH sensor, thermal sensor, analog
an d digi tal data processing, and the I2C communi cation interface. F eaturing a g ood reliability over time,
high accuracy, and low hysteresis, it is an ideal solu tion to b e used in various tempera ture a n d humidity
related IoT applications.
Temp&Hum 10 click is supported by a mikroSDK com pliant l ibrary, which inclu des functions that
simplify softw are development. Thi s Click board com es as a fully tested produ ct, ready to be used on a
system equipped with the m ikroBUS socket. Temp&Hum 10 click can measure the humidity in the range from 0 to 100 %RH and
temperat ure in t he range from 3 0 C to +100 C, with the typical accuracy of 3 %RH and
0.4 . It consumes small amoun t s of power while in operation, delivering proce ssed and
calibrated measurement values over the I2C interface . Thanks to its high reliability
and longterm stability, Temp&Hum 10 click is perfect ly suited for battery operated
weather stations, thermostats and humidistats, microenvironment centers, respiratory
therapy applications, ai r conditione rs, and other similar applications. Due to its low power
consumption, this Click board is a good solution for developme nt of IoTbased and
battery pow ered a pplications.
HOW DOES IT WORK?
The main component of Temp&Hum 10 click is the BPS230, a re lative humidity and
temperat ure sensor with IC Interface, by Bourns. This sensor IC i ntegrates two very
accurate sensing components: temperature sensor, and r elative humidity sensor. By
utilizing the proprietary manufacturing te chnology, this sensor integrates the complete
temperat ure and humidity measure ment system on chip. The output data is processed and
compensated by the BPS230 sensor IC itself, requiring only basi c conversion formulas to be
applied within the firmware of the host microcontroller (MCU). These conversi on formulas
are gi ven in the BPS230 datasheet and provide readings in C and %RH, directly.
The BPS230 incorporates an accurate bandgap temperature sensor, which can measure the
temperature in t he range between 30 C and 100 C while retain ing accuracy of 0.4C,
typically. The accuracy is even greater i f the ra nge is narrowed down: when used over the
range between 10C an d 70C, t he typical accuracy is 0.1 C. Also, the reproducibility of
the temperature measurement is very good, in the ran ge of 0.1C . The BPS230 se nsor IC
can be reliably used for prolonged periods of time.
