1-Wire Battery Management Smart Battery Monitor with Temp Sensor

Type/designation DS2438Z+
Housing SOIC-8 (SMD)
Supply voltage 2.4 V to 10 V
Function
  • Temperature sensor
  • Analog Input 0-10VDC (VAD)
  • Analog Input 0-250mV, +/- (Xsens)
  • Measurement Operating voltage (VDD)
Operating temperature -40°C to +85°C
Details See data sheet

The DS2438 is a Smart Battery Monitor and is used in its original function as a mobile phone battery monitor.
For automation, especially in the smart home area, it is also used for other functions:

  • as voltage meter (supplies the bus voltage (VDD)
  • as thermometer - the temperature is measured
  • AD-Converter (VAD) - is used to measure humidity or brightness
  • Current input (XSENS) - freely available

Hint:
We recommend to connect a 0.1µF capacitor (ceramic) in parallel to the 1-Wire device, i.e. from 5V to GND. The capacitor should be placed as close as possible. This increases the stability of the entire 1-Wire network.

1-Wire Bus Coupler USB Pro, isolated
1-Wire Bus Coupler Pro with USB interface, isolation and external power supply With the professional 1-Wire Bus Coupler USB V3 a stable and electrically isolated connection of the 1-Wire network and a PC, mini computer (e.g. Raspberry Pi) or to many other controllers is established. The 1-Wire Bus Coupler USB is compatible with the serial version of Maxim, DS9097 and DS9097E, and works with a standard DS2480 1-Wire master device. By using the 1-Wire standard interface module (DS2480), the 1-Wire bus copller is compatible with all controllers that support this module. These are for example IP-Symcon, FHEM, OpenHub and many more. A special highlight of the 1-Wire Bus Coupler USB V3 is the external power supply. This significantly increases the operational reliability of the data connection to the computer and prevents problems caused by unreliable USB power supplies. The use of more expensive USB hubs is no longer necessary.For the 1-Wire network the 5V output voltage is provided. The insulation prevents interference from and to the PC and reduces possible "electrosmog" in the house. The insulation also increases electrical safety.Individual 1-Wire sensors can be connected directly. For a 1-Wire network, the use of a 1-Wire hub is recommended. Data interface USB 1.1, with FTDI FT232RL Chip (Virtual COM Port) Compatibility To DS9097U 1-Wire Adapter SerialApplicable for many software, such as OWFS, IP-Symcon, FHEM, which is intended for the DS9097U (DS2480 device) Drivers for different operating systems in the download area of this article.
