It can be used to measure environmental temperature and to directly switch ON\/OFF cooling and heating devices, performing all the functions of a thermostat.\u003c\/p\u003e \u003cp\u003eThermostat Click carries the MAX7502 IC digital temperature sensor, that also provides an overtemperature alarm\/interrupt\/shutdown output, and an SN74LVC1G126 single bus buffer from Texas Instruments. MAX7502 IC can measure temperatures from -25°C to +100°C, within the accuracy of ±1.5°C.\u003c\/p\u003e \u003cp\u003eThe G6D PCB power relay can control up to 5A, 250V AC\/30V DC loads.\u003c\/p\u003e \u003cp\u003eThe Click runs on either 3.3V or 5V power supply and communicates with the target MCU over I2C interface.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eTEMPERATURE RANGE\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe IC can measure temperatures from -25°C to +100°C, within the accuracy of ±1.5°C.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eMAX7502 TEMPERATURE SENSOR\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eMAX7502 temperature sensor measures temperature, converts the data into digital form using a sigma-delta ADC, and communicates the conversion results through an I2C-compatible 2-wire serial interface.\u003c\/p\u003e \u003cp\u003eIt accepts standard I2C commands to read the data, set the overtemperature alarm trip thresholds, and configure other characteristics.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eLOW POWER CONSUMPTION\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThe MAX7502 temperature sensor typically uses only around 250 µA, and in shutdown mode around 3 µA. With such low power consumption, it is very suitable for home automation devices.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eENABLE\/DISABLE THERMOSTAT FUNCTIONALITY\u003c\/strong\u003e\u003c\/p\u003e \u003cp\u003eThere is also the TE (thermostat enable) pin on the mikroBUS� pin socket for enabling (high level) or disabling (low) of the thermostat functionality. This is accomplished via the SN74LVC1G126 single bus buffer with 3-state output IC, which serves as an electronic switch between temperature sensor IC output pin and the relay driver circuit.\u003c\/p\u003e \u003cp\u003eThis way the relay can be permanently disconnected from the sensor IC output. A feature like this can be useful when the sensor IC is only used as an measuring device, or if the thermostat needs to be temporarily disabled.\u003c\/p\u003e \u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003eInterface: GPIO, I\u003csup\u003e2\u003c\/sup\u003eC\u003c\/li\u003e \u003cli\u003eCompatibility: mikroBUS�\u003c\/li\u003e \u003cli\u003eDimensions: 57.15 x 25.4mm\u003c\/li\u003e \u003cli\u003eInput Voltage: 3.3V or 5V\u003c\/li\u003e \u003c\/ul\u003e \u003cp\u003e\u003cstrong\u003eDocuments:\u003c\/strong\u003e\u003c\/p\u003e \u003cul\u003e \u003cli\u003e\u003ca href=\"https:\/\/cdn.sparkfun.com\/assets\/8\/8\/1\/9\/2\/Schematic-20298-MIKROE_Thermostat_Click.pdf\"\u003eSchematic\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/www.mikroe.com\/mikrosdk\"\u003emikroSDK\u003c\/a\u003e\u003c\/li\u003e \u003cli\u003e\u003ca href=\"https:\/\/libstock.mikroe.com\/projects\/view\/1984\/thermostat-click\"\u003eLibStock\u003c\/a\u003e\u003c\/li\u003e \u003c\/ul\u003e","brand":"sparkfun-10","offers":[{"title":"Default Title","offer_id":40531154370645,"sku":"20298:SEN-20298:spark","price":3375.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1034\/1611\/products\/20298_-_MIKROE_Thermostat-_01.jpg?v=1678249786","url":"https:\/\/www.tanotis.com\/products\/sparkfun-mikroe-thermostat-click","provider":"Tanotis","version":"1.0","type":"link"}
