Nettemp Pi Hat - a Nettemp module for Raspberry Pi minicomputer

Description

Nettemp project started for monitor of temperature in flats of author to make a optimalization of rooms heating.

Project assumptions included to provide a ready to use solution for wireless sensors management of temperature, humidity and light measurement and relays control. Software part of project based on simple installer and WWW interface.

Simple use of Nettemp'a:

• Temperature, pressure and humidity measurement in server room
• Heat control at home
• Air conditioning control
• Lighting control

Features

• Compatibility with NETTEMP software
• Extension board for Raspberry PI (version 3/2B/B+)
• Possibility of connection eight separate trees of sensors with I2C/1-Wire interface
• Module is supplied from a minicomputer
• Embedded UART-USB converter (based on chip CP2102 from Silicon Labs)
• Embedded four relays with NO/NC outputs
• Load is connected by screw terminals
• Maximum load of relay pins: 3A/250VAC
• Embedded real-time clock (M41T00S chip from STMicroelectronics)
• Embedded battery holder for RTC support
• Embedded buzzer
• Embedded connector allows to add a minicomputer without any wires
• Embedded pin connector GPIO 28-pin allows e.g. to add TFT display
• Mounting holes for Raspberry PI fastening
• Module size: 146mm x 80mm x 20mm

Nettemp Pi Hat allows to operate sensors, control the attached load and allows to use the touch interface.
