Sensors & Detectors


digilog.pk stocks one of the largest selections of sensors and detectors available in Pakistan — temperature sensors, humidity sensors, motion detectors, ultrasonic distance sensors, gas sensors, current sensors, pressure sensors, soil moisture sensors, flex sensors, and dozens more. Every sensor listed is tested for compatibility with Arduino, ESP32, and Raspberry Pi, with community tutorials and wiring guides available for each.

Why Source Sensors from digilog.pk?

  • Breadboard-ready modules — most sensors come on breakout boards with signal conditioning and decoupling onboard
  • Arduino-tested — library names and example sketches available for every major sensor
  • Wide protocol coverage — I2C, SPI, UART, and analog output sensors all in stock
  • Pakistani projects focus — gas sensors for LPG detection, soil sensors for agriculture, current sensors for solar monitoring

Sensor Categories

  • Temperature & Humidity — DHT11, DHT22, BME280, DS18B20; for weather stations and climate control
  • Distance & Proximity — HC-SR04 ultrasonic, VL53L0X ToF, IR obstacle sensors
  • Motion & Presence — PIR sensors (HC-SR501), microwave radar (RCWL-0516)
  • Gas & Air quality — MQ-2 (LPG/smoke), MQ-135 (CO2/air), MQ-7 (CO), SGP30 (TVOC)
  • Light & Colour — LDR modules, BH1750 lux, TCS3200 colour, VEML6070 UV
  • Current & Voltage — ACS712 (5/20/30A), INA219 (I2C power monitor), ZMCT103C
  • Pressure & Altitude — BMP280, BMP388, MPX5700AP; for weather and altitude logging
  • Inertial (IMU) — MPU6050 6-DOF, MPU9250 9-DOF; for drones, robots, and stabilisers
  • Soil & Water — capacitive soil moisture, rain drop sensor, water level
  • Flex & Force — flex strips, FSR pressure sensors for wearables and robotics

Common Applications

  • Weather station — BME280 + ESP32 + OLED display — see Displays & Modules
  • Smart irrigation — soil moisture + relay + pump control with Arduino
  • Gas leak alarm — MQ-2 + buzzer + GSM alert module
  • Drone flight controller — MPU6050 IMU + Arduino — see Robotics
  • Energy monitor — ACS712 + ESP32 for solar panel current logging — see Solar & Inverter

How to Choose

  1. Accuracy requirement — DHT11 ±2°C; DHT22 ±0.5°C; DS18B20 ±0.5°C with 12-bit resolution
  2. Interface — I2C for multi-sensor buses; analog for simplest code; UART for GPS and GSM
  3. Range — match sensor range to your measurement; HC-SR04 covers 2cm–4m
  4. Power budget — check sleep current if battery powered; PIR sensors can run on µA in standby
