Learn how to build your own IoT temperature logger with data uploaded to the cloud. This project uses itbrainpower.net dual SIM full-size GSM shield [a-gsmII] for data transmission (or itbrainpower.net dual SIM full-size GSM GNSS shield [b-gsmgnss]) and Dallas/Maxim 18B20 1wire temperature sensor. Required time: 30-45 minutes – hardware side 30-60 […]

itbrainpower.net l-LTE v1.07 4G/LTE CAT 1 shield and l-LTE v 1.07 4G/LTE CAT 4 shield, the smallest 4G/LTE shields available today, have one high-performance GNSS [GPS+GLONASS] engine embedded. By default, the GNSS antenna circuitry is configured for passive antennas [does not have enabled the GNSS antenna power supply circuitry]. Even […]

The main purpose of this “how-to” article it is to guide you on how to make a convenient and elegant modular GSM or 3G hardware platform using an Arduino Pro Mini (and related) board, a j-328GSM3GLader Arduino Pro Mini adapter board and c-uGSM / d-u3G / h-nanoGSM modem shields. The purpose of a programmable GSM interface is to be able to communicate with electronics / hardware directly via the cellular network (SIM card required), without the need for a cell phone. You may use such a platform as a mobile IoT interface (access sensor data remotely, or control actuators) or as an SMS / GPRS / DTMF automation platform.

Build yourself your own Arduino temperature SMS alarm – thermal monitoring system having MAXIMUM and MINIMUM temperature thresholds, keep alive messages and (oldies but goldies as) SMS paging and remote ARM/DISARM system. You can supervise one or more 1WIRE temperature sensor(s) and page via SMS the “heating and chilling events” and keep alive messages, including last temperature.

This project will show you how fast you can build your own alarm system capable of supervising one or more magnetic contacts and inform you via SMS of the “burglar event”. You even have the possibility to control (ENABLE/DISABLE) the alarm system remotely, via SMS commands. For SMS communication purposes one of two pin […]
